How did you get into science? I’m a first generation student who grew up in rural East Tennessee and unfortunately didn’t have a great science education heading into college. I didn’t know science was something I liked and could be good at until college and graduate school was never on my radar. I found geology through my love of rock climbing, and luckily had a professor offer to let me tag along on some field work, which kickstarted my research career. That same professor later encouraged me to apply to grad school and helped me through the process.
How did you learn about scientific ocean drilling? My advisor sailed on Expedition 396, and I’ve been working on samples from that expedition for the past two years.
What is your role on the ship? I study lavas that come from the Earth’s mantle to see what they can tell us about what the mantle is made of since we can’t directly sample the mantle or go see it.
Do you use proxy data in your research? Using the geochemistry of basalts (the type of lava typically erupted on the ocean floor) to deduce what the mantle is made of is a type of proxy work, but it’s quite tricky. There’s still so much we don’t know! I’ve developed numerical models to help constrain the possible chemical make-up of mantle source rocks based on the composition of lavas erupted at the surface.
How does your work contribute to the understanding of our Earth? Continental rifting is a primary tectonic process and major shaper of the Earth, yet it’s still not fully understood. My research tells us about what the Earth’s mantle is doing throughout the rifting process and if/how the mantle conditions control the type of rifts produced.
How are you training the next generation of scientists? My university has a great program called the Undergraduate Mentor Development Program which allows graduate students to be certified mentors for undergraduates interested in doing research. I completed the program my first semester as a Ph.D. student and have been mentoring the same undergraduate student since my second semester. It’s so rewarding to see how excited she gets about science and it’s been great to see her grow as a scientist.
Do you conduct scientific outreach? I spent last semester in a local high school working with geology and biology classes to help bring my science to them, but also to observe and learn from their teachers how to best communicate science to teenagers.
What are your hobbies and interests outside of science? I enjoy reading and outdoor recreation, especially climbing and skiing.
Is there anything else about yourself you would like to share? I do it all for my dog and two cats.
What advice do you have for prospective scientists? Science is for everyone! Scientists are often portrayed in the media as stuffy old dudes that take themselves way too seriously, but we’re just normal people with a lot of curiosity about the world around us.
Fake it until you make it is a big one for me. Imposter syndrome is real, and sometimes it helps just to keep in mind that a lot of people feel like they’re faking it when from the outside they’re obviously crushing it.
Hi folks, I’m Roxanne and I’m currently a PhD candidate over at Yale University in the Earth and Planetary Sciences department. As a vertebrate palaeontologist and evolutionary biologist, I spend a lot of my time wondering “how on earth did snakes get to be so damn weird?” and use tools from various scientific disciplines to answer different aspects of this question.
What research are you doing for your PhD?
My PhD research focuses on the question “why are snake skulls the way they are?”
Most modern snakes feed in a very unusual way – they are able to consume prey items significantly larger than the size of their own heads, and do so without chewing or breaking their food up into smaller pieces. If a human were to do this, it would be like swallowing an entire chocolate cake whole instead of cutting it up into slices first. Modern snakes can also control the left side of their face independently to the right side. This enables them to direct their skull bones in way which produces a tooth-laden conveyer belt motion that drags food into their mouths. Pretty useful when you have no hands to help you eat! These behaviours are only possible due to the unique way modern snake skulls are built – but how these novel anatomical features have arisen over evolutionary time is not yet well understood. When in geological history did these key anatomical changes happen? Were some parts of snake anatomy only able to change once other features had evolved, or been lost? Are there compromises to having a flexible skull, such as limiting the type of prey snakes can eat, or how strong their bite force is?
To answer these questions, I spend a lot of my time examining snake fossils. The snake fossil record is pretty sparse, especially if you are looking for skull material, but through a combination of new fieldwork sites and rummaging around museum collections, we sometimes get lucky! These fossils help us understand what regions of the snake skull have changed over 60(+) million years, when in geological time modern groups of snakes first appeared, and how small changes in anatomy can lead to big differences in an animal’s feeding behaviour.
What is your favorite part about being a scientist, and how did you get interested in science? I grew up in the UK and began my university education there too. When it came to picking a place to conduct PhD research, I was excited about the possibility of working abroad, and being able to explore fieldwork in new landscapes and biomes than I was used to. I love that being a scientist can take you anywhere in the world, and you get to discover new places and cultures, whilst still having geeky conversations with folks from different backgrounds to my own.
As a kid, I was one of those people who was always asking the questions and trying to link together what I knew of the natural world. Learning new things relating to prehistoric life and ancient environments was what brought the most joy. As a first-generation student, the concept of going to university was pretty alien, and at that stage in my life, I don’t think I’d even met a scientist who wasn’t one of my high school teachers. I deliberately picked an undergraduate degree which would let me continue to explore multiple science disciplines which ‘traditionally’ were not considered to compliment each other: geology, developmental biology, and evolution and behaviour. By then I knew I loved science but did not want to give up asking questions from these different perspectives. I never thought I’d actually become a palaeontologist – it was one of those impossible dream professions, no different from the musings of a 5-year-old who wants to grow up and become a princess, or a steam train. Midway through undergrad one of my guidance tutors reassured me that not only was palaeontology ‘a real job’ but something that I could build a career in too. He encouraged me to reach out to palaeontology professors around the UK; some of which offered me summer research positions in their labs. After getting a taste of doing research full-time, I knew I wanted that to be a large part of my vocation.
What advice do you have for up and coming scientists? It’s never too early to build yourself a network of scientists. Introduce yourself to researchers whose work you enjoy, respect or are excited to ask questions about. Whilst this can seem daunting, there’s a lot of empathy in the field. For every experienced academic, there was once a shy undergraduate feeling out of their depth – so those scientists worth talking to will be kind to someone new to academia. The vast majority of modern research is not possible without collaborating with others – so find scientists who value you as a researcher and a thinker, irrespective of your ‘academic age’ or academic position. These are the folks you will likely grow the most from, and also have the most fun being a scientist with.
Tell us a little bit about yourself. Greetings! I’m Jacqueline Silviria. I’m originally from Los Angeles, California. I received my BS at the New Mexico Institute of Mining & Technology, my MS at the University of New Mexico, and am currently working on my PhD at the University of Washington, Seattle. I’ve been a fan of Japanese animation for about a decade, and I collect out-of-print DVD and BluRay boxsets of 1990s-early 2000s series, as well as rare figurines and statues. Recently, I also started collecting 1990s animation cels from series in my media library. Expect me to visit every major North American Japantown and Chinatown at least once in search of vintage merch! I also seek out rare natural history books and articles from the early-mid 20th century, especially those from China, Japan, and the former Soviet Union. That hobby has become much less expensive thanks to internet archives and interlibrary loan services!
What kind of scientist are you and what do you do? I’m starting my second year as a PhD student in the UW Department of Earth & Space Science, working in Gregory Wilson Mantilla’s lab in the Department of Biology and the Burke Museum of Natural History & Science. My main research interests are the morphometry, phylogenetic systematics, and biogeography of ungulates (hooved mammals). I’m currently focused on the postcanine dental anatomy of the earliest ungulates in North America, from the aftermath of the Cretaceous/Paleogene (K/Pg) mass extinction. I employ photogrammetry and micro-CT scanning to make 3D models of ungulate jaws and teeth, for collection of shape data important for distinguish different species. I’m planning to print 3D models for use in our Evolution of Mammals and their Ancestors undergraduate course, as well as public outreach events at the Burke Museum. Every summer, I help the Burke’s Hell Creek Project organize and instruct the DIG Field School, which brings K-12 teachers to our K/Pg field sites in Montana, so they bring back the wonders of vertebrate paleontology to their own classrooms. I also recently started The Last King of the Jungle Discord sever for professional researchers to discuss the latest news in mammal paleontology.
What is your favorite part about being a scientist, and how did you get interested in science? My first job in paleontology was as a student curator for the invertebrate paleontology teaching collections at New Mexico Tech and the New Mexico Bureau of Geology. It was through this position that I met Thomas Williamson at the New Mexico Museum of Natural History & Science, who noticed my enthusiasm for mammalian evolution and systematics; I would later work as a curatorial assistant at the museum while working on my Masters. Since then, my favorite part of research has been collections curation and management, because it allows me to look at material that would otherwise be forgotten. I especially enjoy specimen photography and am quite proficient at focus-stacking images of mammalian teeth (I thank Tom for teaching how). I also taught myself computer software for cladistic analyses of evolutionary relationships; I’m most familiar with the maximum parsimony approach, but I’m hoping to get more fluent in maximum likelihood methods. Such analyses permit a get fresh, quantitative perspective on species and taxa that may have been ignored since their original description, and thus not securely placed in the tree of life.
But while I consider myself a collections-based “armchair” researcher, I also enjoy paleontological fieldwork for the simple pleasure of visiting exotic and remote localities I normally wouldn’t have the time or money to go to. Picking live anthills for mammal teeth and other small fossils is a favorite task of fieldwork, if only for the adrenaline rush of racing against the clock before the ants unplug their nest! And even if I have a bad day at a fossil site, I know I will have learned enough about the geology of the area that it’s worth going back the next year.
How does your work contribute to the betterment of society in general? As a transgender woman, I heed the call to serve as a good role model for other LGBTIQA+ students and early career researchers in geology and paleontology, especially given the current political climate in North America and Europe. I think great strides have been taken at LGBTIQA+ representation and equality at paleontological societies compared to other scientific institutions, but more work needs to be done so that we don’t backtrack and repeat the mistakes of the past. Additionally, I’m the first person in my immediate family, trans or otherwise, to pursue a PhD degree.
More importantly, as a collections-based researcher, I feel a responsibility to preserve and protect our public cultural and scientific heritage, particularly when many institutions face the threat of defunding or even privatization. The material housed in natural history museum and university collections comprise an irreplaceable knowledge base for systematic research that permits broader scale “big picture” analyses, like ecological studies on the effects of climate change. I hope that my future outreach efforts online and at the Burke Museum will promote collections curation and management, especially at paleontological institution, so up-and-coming students will see at as an invaluable public service and not simply “rock hounding” or “stamp collecting”.
What advice do you have for up and coming scientists? My advice is to be flexible with approaches and interests in the very beginning, but later consider specializing in what gives you joy and what you excel in. When exploring research programs in your field, acknowledge that ideas and procedures evolve over time, and that absolute certainty is impossible in the natural sciences, but still work towards honoring and preserving the accomplishments of your academic predecessors for future generations. In other words, be anti-authoritarian but authoritative (to paraphrase Niels Bonde’s retrospective on Colin Patterson). And do not shun systematics/taxonomy because it can be difficult for poorly studied groups of organisms; without it, the language of science risks becoming inscrutable garble!
Tell us a little bit about yourself. I have a Bachelors in Marine Biology and love to admire nature and the fascinating designs evolution and the planet have produced. I do art in my downtime, specifically painting, although I have interests in ceramics, woodworking, and sculpture. Most of my inspiration for art comes from interesting animals or landscapes. Swimming, snorkeling, and hiking are things I love to do given the opportunity. I like to write, discuss philosophy, and have been a martial artist for over ten years.
What kind of scientist are you and what do you do? I am a Geology Master’s student at the University of South Florida, Tampa. I study food webs in aquatic environments and the transfer of different nutrients and metals between fish species. I am interested in using geochemical methods and data to look at ecological relationships. Specifically, I analyze tissue samples and look at proportions of different compounds to determine what level of predator they are and how quickly those chemical signals can change over time. I am also hoping to incorporate computer programming into my research by developing data processing code that can be used by any researchers using similar data.
What is your favorite part about being a scientist, and how did you get interested in science? My favorite aspects of science are the creative challenges associated with it, such as experimental design and problem solving, and the opportunity to constantly be learning new things. In environmental science, there are multiple fields that intersect including biology, chemistry, geology, physics, ecology, and so on—in my research, I am constantly reading and learning about these things as part of my job. I was always interested in science as a kid, and specifically ocean life. Curiosity about how those organisms lived and what determined how much or how little we knew of them made me want to study science.
How does your work contribute to the betterment of society in general? I am hoping that the methods I am studying for my thesis can be applied to a variety of fields, including future geochemistry work, conservation biology, and fisheries management. One advantage to the geochemical methods I use, which include mass spectrometry, is that small sample sizes can be used. This means that we can monitor live fish populations without using lethal methods. The techniques are being studied with fish populations, but these can hypothetically also be applied to other biological systems, to medical research, and to different subfields of geology.
What advice do you have for up and coming scientists? My biggest advice for other people (like me) who are beginning or early-on in their academic careers would be to focus on what you find interesting, even if you don’t have the ability to study that right away. Part of that drive or curiosity, in my mind, is critical to long-term success in science. My second piece of advice would be to learn as many skills as possible. Outside of books and coursework, knowing things like knowing how to use hardware tools or how to write computer code can be very useful. Knowing PVC plumbing can help with knowing how to put together an aquarium for study animals—and it’s stressful to only be learning it once the skill is needed immediately. Diversity in experience is also something that generally helps with confidence and being able to find a place to make yourself useful.
Hey there! My name is Michaela and I am a cat-lady, sci-fi-nerd and hobby illustrator, who gets paid to hang out on tropical beaches a lot – how is that possible, you ask? Well… I got lucky.
The first time I got lucky was when I was eight years old and announced to my flabbergasted parents that I had decided to become a paleontologist like my hero at the time: Dr Alan Grant (also known as “guy with the cool hat in Jurassic Park”). My parents, who did not have the opportunity to go to university themselves and had never heard of paleontology, would have been perfectly justified to believe that my career goals were nothing to be taken seriously and move on, but they did not. Instead, they bought piles of dinosaur books, spent countless hours in museums and corrected everyone who confused paleontology with archeology with admirable patience. I was still set on becoming a paleontologist 11 years later, when I first set foot in the geoscience department of University Bonn. It is certainly not my parents’ fault that I didn’t.
The second time I got lucky has to do with the fact that becoming a paleontologist in Germany requires you to become a geologist first. It only took a couple of rock identification classes for me to realize that yes, dinosaurs are amazing, but evolution is only one of the natural processes that shape our planet, and the others are even more fascinating to me. I had never thought about mountains being crumbled into tiny pieces by weather and time, these pieces then being transported by wind and rivers into the ocean, while being reshaped again and again, before they come to rest somewhere along the way. As a sedimentologist you look at the pieces of rock that are shuffled around on the planet’s surface and make them your own personal window through time. Sedimentary rocks let you study rivers that rushed by millions of years ago or watch coral reefs grow and die and regrow in a millennial cycle. By the time I finished my bachelor’s degree I was hooked. I still have a cool dinosaur model on my desk, but sedimentary rocks are what is on my mind, what pays my bills (sometimes) and what got me into another field of science with a very relevant application: sea level research.
This brings me to the third time I got lucky. This one really did not feel like luck at the time. In 2016, I got rejected for three possible projects for a master thesis and thus one day stumbled into the office of the new professor at the department, who had nothing to do with sedimentology. I stood in the doorframe a little desperate and ready to take whatever the man would offer. This professor, who would later become my PhD supervisor and close friend, offered me an opportunity to study sea level change at the coastline of Oman – turns out you can squeeze sedimentology into any project.
Sea-level and coastal research became the focus of my scientific journey and Oman somewhat of a second home. For my masters and PhD, I studied beachrock. That is essentially beach sand that turned into hard rock, because a natural cement forms in between the individual grains of sand. Think of it as a bunch of sand and gravel glued together by carbonate, the white stuff that forms in your kettle or washing machine. Beachrocks are not only very cool, but also useful when we are trying to understand how sea level changed in the past and make assumptions on how it is going to change in the future. Climate driven global sea level rise might be something you are familiar with, but that is only part of the story. Yes, global sea level is rising, but the land might move as well. In some areas it is sinking, making global sea level rise an even bigger problem, in other areas the land is uplifting, mitigating the effects of global sea level rise. Beachrocks can help to understand what is happening on one individual stretch of coastline, giving coastal communities the chance to adapt and me the chance to hang out on tropical beaches a lot. While on the beach, I study the sedimentological characteristics of the beachrock and take samples. The samples are then taken to the lab – either to determine their age or to use a microscope to look at the cement between the grains.
Right now, I am (sadly) neither at a beach nor in a lab, but at a desk in Germany preparing for my PhD defense and applying for postdoc positions – a tedious task that involves a lot of rejection. I don’t think there is a career in science without tedious tasks, be it repetitive lab work, marking piles of exams or never-ending application forms to fill out. Nevertheless, science allows me to keep my inner child alive, it allows me to follow my curiosity, all while making a contribution that helps coastal communities deal with the threat of sea level rise. I don’t know if I’ll get lucky one more time and be allowed to do this for a few more years, but I certainly hope so. One thing that I wish I had known from the beginning is that people are more important than the academic disciplines they belong to – looking back I would always choose a mentor outside my specialty with whom I have a great connection over the greatest expert in my field who does not care about me.
Update: By the time this is posted, I successfully defended my PhD thesis and started a Postdoc position in Heidelberg, Germany, where I get to teach sedimentology (yay) and work on a grant proposal for studying the incorporation of trash into beachrock on the Bahamas (even bigger yay)!!
Tell us a little bit about yourself. Outside of science I enjoy reading manga, collecting Pokémon cards, and playing video games.
Describe what you do. I am an undergraduate researcher. I recently finished a project which involved entering geographic information of echinoderms (animals like and including sea stars, sea lilies, sea cucumbers, etc.) into a database so that we could analyze their biogeographic patterns (how the animals moved through time and space) in the geologic record.
I have done class visits with groups of fourth graders as a part of the Scientists in Every Florida School program to teach them about geology.
Discuss your path into science. I used to want to be a lawyer for as long as I can remember, but on my 17th birthday, I visited the American Museum of Natural History and was smitten with their dinosaur exhibits! After leaving, I was unsure if I wanted to continue pursuing a career in law, so I did some basic research of how much I could expect to make as a paleontologist (to make sure I could still support myself and a family) and decided to commit to the switch. After that, I have been pursuing dinosaur paleontology as best I can!
Discuss other scientific interests. I’m very interested in birds and reptiles, specifically snakes. If I couldn’t study nonavian (non-bird) dinosaurs, I would study one of those groups of animals in the fossil record. I’ve also become quite attached to crinoids since starting my undergraduate degree, so they would be my invertebrate pick!
How does your work contribute to the betterment of society in general? Hopefully, with the echinoderm geographic data that I’ve collected, we can better understand of echinoderm evolution through time as well as how they dispersed across the world over time.
I hope that I’ve convinced the classes I’ve visited that geology is a science that rocks! More than that, I also hope that I’ve made them more curious about how our world works, and to keep asking amazing questions and finding equally amazing answers.
Is there anything you wish you had known before going into science? Mainly, what classes I would have to take. In my case, I had multiple major options, but didn’t look too far into them. I’m very happy where I am now, although I’m sure there is an alternate universe version of me that is going down the biology route.
Have you received a piece of advice from your friends/mentors/advisors that has helped you navigate your career? I’ve gotten good advice about grad school. In particular, I should be reaching out to professors I would like to work with a good while before applications are due.
Tell us a little bit about yourself. Hi! My name is Blandine, and I am a master’s graduate in vertebrate paleontology. I specialise on dinosaurs (taphonomy, histology). I did my geology bachelor’s degree in Lille (France) with an Erasmus+ mobility in Tomsk (Russia), followed by a master’s degree in paleontology done in Lille for the first year, and an Erasmus mobility in Bonn (Germany) for the second, with my master’s thesis. Outside of paleontology, I am interested in modern Japanese literature, gothic fiction, taking care of plants and animals. But to be honest, I’m having the most fun when I’m in a museum!
What kind of scientist are you and what do you do?My career is only beginning, and I like to try out everything related to paleontology.
For my master’s thesis, I had a research project on green-colored dinosaur bones from Utah (USA). The remains belonged to several diplodocines (large long-necked dinosaurs), and an unusual fossilization turned them green. Histology (study of bones microstructures) is a technique which has many uses, one of them being the determination of the age of an animal by the observation of its bone tissues. This method is particularly useful in bonebeds where dinosaur remains have been mixed because of river flows (for example). Through the observation of bone sections under the microscope, I could determine that the diplodocine remains came from animals of different ages, which meant several dinosaurs’ carcasses were mixed in the quarry.
Before that, during my bachelor’s, I learned dinosaur bone preparation in the vertebrate paleontology laboratory of the Tomsk State University. It’s a tedious work, but you really learn a lot by preparing the fossils by yourself. There are so many details you can miss when you observe a bone taken out of its context! The surrounding sediments, the geometry of the deposition, the state of preservation of the remains… all those clues are very important when doing a paleontological investigation! I see things in this way: a vertebrate paleontologist is often like a medical examiner in a murder case. When the body is removed from the crime scene, they are able to tell the cause of death, but not who killed the victim. To get the whole picture, we need the crime scene as well. For paleontologists, this corresponds to the quarry/bonebed, or at least the sediments around the bones. This is what field excursions, and thorough documentation on excavations are for!
During the bachelor years I had in Lille, I worked as a curating assistant for the geology department of the Museum of Natural History, and helped organising several public outreach events, giving talks on the need of paleontology in our societies to understand today’s climate emergency.
A few months ago, I helped dismantling the “Big, Bigger, Dinosaurs” exhibition at the Museum Koenig in Bonn, and returning to this kind of environment after a 3 years break felt really good. Since then, I occasionally help setting up and dismantling exhibitions around dinosaurs, and it is so much fun! (PS: I created an instagram account to try to share the behind the scenes of dinosaur research and exhibitions… @dinosaurs_forensics 😉 )
What is your favorite part about being a scientist, and how did you get interested in science? When I was a child, I developed an interest for bones early on. I would collect bones and skulls from diverse animals I would find in the fields, clean and sort them in different categories. As my mother thought this was a horrible hobby for a little girl, she got rid of my collection as soon as she found out it was not a short-lived interest. I then moved on to snail shells, but this collection was really stinky, and ended up in the trash like the former one. To me, keeping those bones and shells were like preserving memories of what once was. I wanted to understand what had happened to those animals, and their remains were a way to find out. One day, a friend of my parents showed them a plant fossil. It was a trace of a thing that lived in the past, it was beautiful, did not stink.. and my parents liked it? From that moment on, I started asking questions about fossils and collecting them. My dad brought me to the Museum of Natural History in Lille, and there I could show my treasures, get answers about them, and see which stories could be uncovered through fossil remains. I decided I would become a paleontologist one day. Growing up, I received a great support from my dad, one museum curator, and three school teachers who encouraged me to follow my passion, despite everyone around saying that I would “never make it” in paleontology.
My favorite parts about being a scientist are to question the current knowledge, go on field excursions to look for fossils in places where nature has been untouched, and also try to close the gap between scientists and the public. In the same way older people made me want to do paleontology and pushed me to follow my dreams, I want to transmit the knowledge and will to understand our world to younger generations. I love speaking to kids, grandparents, families who want to know about what was, and what extinct forms of life can tell us about our present and future.
How does your work contribute to the betterment of society in general? Dinosaurs make kids and adults dream and wonder, and even if this field of paleontology can be considered as “less meaningful” regarding climate change than micropaleontology as an example, I like researching about them just for the sake of knowledge. Why did they look this way? What were their habits? Why were they so big?
I believe there is nothing wrong in trying to answer questions which do not appear as “useful” for today’s societies. All questions deserve to be answered. On the other hand, understanding dinosaur’s ecology, biology, environment and habits definitely help us refine the knowledge we have about evolution and other aspects of the living.
Dinosaurs are also useful in another way: as they are part of the worldwide pop-culture, they are very often the first step into paleontology for many people. Through dinosaurs, it is possible to speak to people about fossils, geology, evolution, extinction events. As a result, for public outreach, scientists (including me) use them as an introduction to topics such as climate change. That’s why so many scientific articles use “dinosaur” in their title, even when those animals are not involved in the paper.
What advice do you have for up and coming scientists? “Do or do not. There is no try.” if you want to do science, go for it. Do your best, always, and if it does not work, you won’t have any regrets because you did all you could to make it happen. And when obstacles will come along the way, never forget that for each problem there is a solution. If you have passion, you will get to meet similar-minded persons who will help you reach your goals, and you will end up finding your spot in this field.
If you are a LGBTQ+, disabled, POC or woman-identifying person: there is space for you in science. Together, we should and will make this environment a safer place, where we all can grow equally. We need diversity, please don’t give up on your dreams.
Hi! I’m Danijela, a first year PhD student at FAU University Erlangen-Nürnberg in Germany. I am from Serbia, but I have been living in Germany since 2018 when I started a master’s degree in Paleobiology at FAU.
What kind of scientist are you and what do you do? My research is all about corals and reefs through time. I study the evolution of scleractinian corals also known as stony corals, from the time when they first appeared in the mid Triassic, around 250 million years ago until today. I am so happy to be working on these super organisms because everything about them is fascinating – their biology, ecology, and geology. They build coral reefs in shallow tropical seas which harbour the highest diversity of organisms in the ocean. They also live in a mutually beneficial relationship with tiny algae which perform photosymbiosis while living within the coral’s soft tissue and provide corals with 90% of necessary nutrients. Corals are also hunters at night, and some of them can live at depths of thousands of meters. Unfortunately, their future fate and the fate of many organisms that live on reefs and depend on them are also affected by the climate change and other anthropogenic disturbances such as pollution and overfishing. I could talk for hours about how cool are corals and reefs they form, and how we need to do everything we can to keep them from disappearing, so I have been lucky that this semester I have been given the opportunity to teach the course on geobiology of reefs to our Master students (in English of course!).
For my research, I am particularly interested in how their morphological characters changed through time and if their extinction risk was related to changes in their traits. For example, in my Master thesis I looked at changes in corallite diameter through time. Corallite is a skeletal cup in which the coral polyp sits. The size of the corallite could be related to their efficacy of obtaining nutrients and I was interested to see if this change was related to major warming events or reef crises in Earth’s history. This would help us predict their future fates under global warming scenarios. For this kind of research, we used datasets such as the one we created by collecting data from the literature into the database called ART which stands for Ancient Reef Traits. This database has been built for the past two years by the team of scientists at Paleo group at FAU and soon will become available to everyone.
How did you become a palaeontologist? Unlike many paleo people, my story of getting into the paleo world is untraditional one. I wasn’t into dinosaurs when I was little, and I didn’t even know much about palaeontology until a few years ago. However, I always loved nature and all its wonders, and have been fascinated by both the biology and Earth’s history. In high school I was also interested in social sciences and languages so choosing a bachelor’s degree was very difficult for me. It was one of the hardest decisions I had to make because at the time I believed that I would have to be forever stuck in the chosen field. But I actually switched fields several times. I started by studying a bachelor’s degree in environmental science at University of Belgrade in Serbia. Then, I did a master’s degree in applied ecology (IMAE) which was funded by the Erasmus Mundus scholarship program, and it meant that I had to change universities during the two years. It was one of the best experiences of my life – not only did I get the opportunity to study at Universities in France and Portugal, but I have also met many amazing people and made friends for life. Within this program we got to go on a month-long field trip in Ecuador and experience and study different ecosystems. From hiking at 4000 meters in the Paramo ecosystems in the Andean mountains, over living in the heart of the Amazonian rainforest, to swimming with hammerhead sharks in the Galapagos Islands. After all these experiences I was sure I wanted to be a scientist. My master thesis was about the diet of Antarctic penguins (no, I didn’t get to go there) and at the time I was in search of a PhD program where I could get the opportunity to go to the Antarctic and study penguins. However, during that search I also stumbled upon several palaeontology projects, and I was simply drawn to it. Palaeontology as a field offered so much more than contemporary ecology – it was the intersection of ecology, biology and geology and many other fields and it felt just right for me. Since I didn’t have any formal education in palaeontology, I wanted to learn more about it. So, to the shock of many I decided not to do a PhD, but to do another master’s degree in Paleobiology. It was maybe one of the hardest decisions I made and it set back my scientific career by a few years, but it was definitely the right one! I am now grateful to myself that I was brave enough over the course of years to follow my heart and change fields!
What advice do you have for up and coming scientists? My message to young prospective scientists is that it’s never too late for anything in life and especially not for pursuing your passion. I still believe that having to choose a career path when you are 19 years old (or even a bit older) is way too early. So, give yourself a time if you need to explore your interests. Most importantly, don’t allow yourself to be stuck in a box – being interdisciplinary and having many different skills are the great advantages for a scientist. So, believe in yourself and just follow your own path, because doing what you love is the greatest reward of all.
Hi! My name is Haley and I’m an undergraduate researcher at the University of Florida (UF) pursuing a Bachelor of Science in Microbiology and Cell Science. Before transferring to UF, I received my A.A. from Santa Fe College.
What do you do? I perform research in the field of astrobiology, the study of whether extraterrestrial life exists, and if it does, how might humans detect it. A common strategy for determining whether a planet used to, or currently does, contain extraterrestrial life is to look for biosignatures. A biosignature is anything that provides scientific evidence of past or present life. Rocks on Earth are commonly used for testing and validating biosignature detection strategies. However, rocks on Earth don’t perfectly match up to the rocks we would see on other planets, specifically Mars. One of the differences between the rocks on Earth and the rocks on Mars is that the rocks on Mars’ surface are much older (> 3.5 Ga) than those on Earth’s surface. This major age difference brings into question how accurate our Earth-sourced Martian analogs are. In order to address this question, my research focuses on how effective a specific biosignature detection strategy called tetramethylammonium hydroxide (TMAH) thermochemolysis is at detecting organic molecules in rocks ranging from 1.1-3.2 Ga.
My research directly supports multiple NASA astrobiology missions; however, its biggest impact is seen when interpreting the data gathered by NASA’s Curiosity rover which landed on Mars in 2012. Curiosity has performed TMAH thermochemolysis on Martian rocks and the data from this experiment has been downlinked back to Earth. My research directly helps the scientists at NASA interpret this TMAH thermochemolysis data.
What advice do you have for aspiring scientists? Understand and accept that science requires perseverance. Nothing about science is easy, but if you can persist in doing something despite difficulty or delay in achieving success, you will go a long way.
Hello everyone. I am a biogeochemist who uses ancient molecules found in lake sediments to investigate interactions between humans and their environment. I am finishing a PhD in biogeochemistry at McGill in Montréal, Québec. I like skiing and ice skating, jazz, and when the earth is not frozen over I spend my lot of time bike-camping and swimming outdoors. I moved to Canada after a degree in geological sciences in England/California and working as an environmental consultant, a water engineer, and as a research assistant at the Complutense University of Madrid.
My current research looks at how the lowland Maya interacted with their environment and how they responded to climate change over 3,300 years. I take samples from Central America, extract organic molecules known as lipids and analyse them using different methods. I use plant waxes as a proxy for vegetation and hydrological change (how wet or dry it was) in the past, polycyclic aromatic carbons (from the incomplete combustion of carbon) as a proxy for biomass burning the past, and faecal stanols as proxies for population change.
My first chapter shows that population declines in the southwest Maya lowlands are associated not only with drought at multiple times throughout history, but also with anomalously wet periods, and has also highlighted potential efforts to reduce soil erosion as well as the use of night soil (human waste) as fertiliser in the past. This work attracted a lot of media interest, including from the CBC, Haaretz, El Mundo, and Archaeology Magazine, and will be vulgarised in the magazine Le Climatoscope. It also forms part of the chapter “Climate Change and Variability in the Protoclassic” in Remaking Maya Civilization, Social and Political Transformations in the Protoclassic Maya Lowlands.
Now I am in the process of writing my thesis, which I will submit in December, and working with a digital artist to create a virtual Itzan, the archaeological site where the samples I have analysed were taken from. I think it is important for people to know that ancient societies were affected by climate change and by looking at responses to environmental change in the past how we might better understand anthropogenic climate change today and in the future. I am particularly interested in migration as climate change adaptation and am a member of the McGill Refugee Research Group.
Most students are fortunate enough to be on campuses with interesting seminars and public lectures in different departments that you can attend and make connections between your interests, your research and what is happening in different areas and at different scales. This is interesting and can be fruitful, and helps prevent you from getting stuck in the rut of your niche bit of research. Attending talks in anthropology, geography, and social sciences has given me new perspectives for my thesis, where the question I am researching requires an interdisciplinary approach.
