Elizabeth Rohlicek, Podcast host and Paleobiologist

Tell us a little bit about yourself. Living on Vancouver Island in the Pacific Northwest, I’m so lucky to be in such a great environment. I love packing up my car and going for hikes, camping, island hopping, and paddling on the ocean. My summer days are spent reading and camping, and my winter (rainy) months are spent playing board games on my couch in front of the fire after a day of skiing. One of my passions outside of my research is my podcast Below the Tide. I get to chat with scientists about their marine research, and make it accessible to the public.

What kind of scientist are you and what do you do? I started my research as an undergraduate project, for course credit. The curator of paleontology at the Royal British Columbia Museum is an adjunct professor at the University of Victoria, where I was completing my degree. I had been volunteering with Dr. Arbour for a couple of weeks before March 2020. In September of 2020 she offered me a project that involved looking through some cabinets of cetacean fossils from Vancouver Island that had been collected over the last few decades. The fossils had never been evaluated nor published on. So I jumped in, and learned about fossils as I went. The fossils are from the Oligocene period, which is a geological time period that defines the time of about 23-33 million years ago. This is such an important time in whale evolution; it is the time where we see toothed whales and baleen whales diverging. Before this time, all whales were toothed, and hunted their food. But something happened in this time period where whales started to grow baleen plates in their mouth, and the fun part is that nobody is completely sure why! A really thrilling part of this work is that the fossils were found on Vancouver Island, where I live. My research is helping to contribute to the fossil record of the North Pacific, and putting Vancouver Island on the map to prove the importance of the fossil record here. Oligocene-aged whale fossils are not found everywhere in the world; there are only select geographic areas where fossils from this time period can be found easily, and it just so happens that one of my favourite beaches on the island is a prime fossil hunting location!

Through this project I did some outreach work through the museum; creating accessible learning material in different media types and presenting my research at the Society of Vertebrate Paleontology conference in 2021!

I discovered this immense passion for public outreach and making science accessible, through this research project. That was what pushed me to start my podcast: Below the Tide. The goal of Below the Tide is to create a space in which marine scientists can share their research and stories in an accessible way to the public. We break down their research and chat about what their path and fieldwork looks like. I love the idea of bringing attention to so many realms of marine science, but also showing that scientists lead such remarkable lives.

What is your favorite part about being a scientist, and how did you get interested in science? I’ve always been into science, since I was a kid. My parents were in the science field, but they always encouraged me to follow my own path. My interest in science was different from theirs – I was really intrigued in the inner workings of ecosystems, and marine science. I moved across Canada from Montreal to Victoria to study marine science at the University of Victoria, and completed a bachelor’s degree in biology and earth and ocean sciences. Through my degree I got really interested in paleobiology, specifically cetacean evolution. My other interest in the scientific field really is science communication. I’m excited to see where my podcast takes me, and I hope making science accessible is something I can continue in.

How does your work contribute to the betterment of society in general? Paleobiology in general is really important for understanding ecosystem and organism evolution, and their responses to changes in the environment. Even looking at cetacean evolution; we can see there was an immense amount of diversity in cetacean populations about 33 million years ago. Today’s cetacean populations are commonly struggling in the face of climate change, and other anthropogenic influences.  We can use the past millions of years of changing climate to assess how populations today may face the current issues. The field of anything paleo related isn’t all about fossils; it also includes ancient climates, ecosystems, influences, changes, and so much more. I love how the realm of paleo is so collaborative and is just one big puzzle.

What advice do you have for up and coming scientists? Take opportunities as they are presented to you, and reach out to people. I’m a believer in no opportunity is a waste of time, it definitely is a growing opportunity. If you start a volunteer position in a lab and realize you aren’t keen on lab work; you’ve learned something about yourself! Congrats! It means that you now know that a career or position in a lab may not be your cup of tea. And on the second point; reach out to people if you want to learn about their research. Ask questions, ask for potential volunteer positions, ask for career advice. The worst that will happen is that they will say no. So if you are interested in a certain field, find someone who is in that field and ask to connect. They are your most valuable resource. That way you can ask all the questions, ask for advice, and network.

Blair Stuhlmuller, High School Science Teacher and Science Communicator

Blair standing in front of the Grand Canyon in Arizona on a family vacation.

I am a high school science teacher and love sharing my knowledge and passion about the natural world with my students and anyone who will listen. I specifically love marine science and geologic history. I currently teach a marine biology course and another course on the big 5 mass extinctions. Both of which I designed myself. I am hoping to branch out beyond just the four walls of my classroom and share the weird and wonderful world of science with others as a science communicator.

I dreamed of being a teacher for a very long time. I loved the idea of being a forever learner and working with the future generations. But I had no intention of being a science teacher until the end of my freshman year of college. I wanted to be a history teacher and was well on my way to getting all my prerequisites done when I took a freshman writing seminar on the History of the Earth. This class expanded my perception of what was history and left me fascinated with deep time, the evolution of life and landforms. I was hooked and set off to get a Bachelors of Science in Geology and Environmental Science. After undergrad, I got a Masters of Education and my Virginia teaching license and then proceeded to move clear across the country to the west coast to explore some of the tidepool studded coasts and more geologically active rocks of California and Oregon.

Now I help inspire the next generation of scientists and planetary stewards. I believe that science is for everyone and do everything in my power to encourage others to give it a chance. You never know what class, lab or cool fact can send you spinning down a different path. The world needs more passionate scientists to answer the next level of questions and help solve the problems of tomorrow. 

When I’m not teaching, I’m typically nerding out on the latest Marvel movie, excessively reading for fun or exploring the beautiful Pacific Northwest. I’m always down for a good hike especially if it ends in a waterfall. I’m also PADI SCUBA certified and love exploring the world under the waves despite how cold the water gets. I do all of these things with my identical twin sister who has stuck with me through every step of my life so far.

Anna Geldert (she/her), Geobiology Undergraduate Student

background: greenery with trees and leaves and grassy area. foreground: Anna hugging a tree trunk and smiling. Tell us a little bit about yourself. Hi! My name is Anna Geldert (she/her). I’m from Minnesota, but I’ve spent the past year living in Vermont where I’m working toward my undergraduate degree at Middlebury College. In my free time, I enjoy reading, writing, practicing music, and playing volleyball on my college’s club team. I’m also a huge outdoor enthusiast, and I always look forward to camping, hiking, canoeing, or skiing with friends and family. Spending so much time outdoors as a kid is one of the factors that sparked my interest in the natural sciences in the first place, and the main reason I am so passionate about sustainability today. 

What kind of scientist are you and what do you do? Currently, I’m working toward a joint undergraduate degree in Biology and Geology. I’m fascinated by the way Earth’s natural systems function, and how they’ve evolved around the world and across geologic time. While I’m not totally sure what direction I want to go in this field, I’m ultimately hoping to pursue a career doing field research in relation to ecosystem response to climate and other anthropogenic change. 

What is your favorite part about being a scientist, and how did you get interested in science? In many ways, my interest in science developed long before I took any classes or considered a career in the field. One of my biggest supporters is my dad, who is a physics teacher. Growing up, he always encouraged me to stay curious and frequently used me as a guinea pig for demonstrations he planned to do in class the following day. I also spent a lot of time camping and hiking as a kid, which sparked my interest in the natural sciences. My favorite part about science is that it allows me to spend time outside with lots of hands-on experiences. Seeing first-hand how something we learned in class presents itself in the real world is really gratifying and reminds me why I wanted to study science in the first place.

How does your work contribute to the betterment of society in general? I hope my work will be used to help human societies coexist with the Earth in a way that makes sense for both parties. For example, last year I studied the potential of using fungal mycelium as a sustainable option for treating acid mine drainage. I think Earth’s natural systems have a lot to offer, and studying them can help us better understand how to act sustainably in our own life.

Science can be whatever you want to make of it. It is such a broad field, and there are so many opportunities to tailor your education and research to something you’re passionate about. Personally, I wasn’t super interested in science until I was able to do more hands-on experiments and independent research.. That was when I realized I could apply interests I already had – such as sustainability and the outdoors – to actual scientific study in Geo-Biology. I would encourage future scientists to keep an open mind and use science as a means to explore whatever sparks their curiosity.

Michael Hallinan, Undergraduate Student

Tell us a bit about yourself. 
My name is Michael Hallinan, and I am currently an undergraduate student at Colorado School of Mines studying for a B.S. in Quantitative Bioscience and Engineering. Although I love science, I am also super passionate about painting, music, and esports! I have a huge fixation on international music and love to analyze the relationships between globalization and culture the same way I enjoy analyzing ecological relationships.

What kind of scientist are you, what do you do, and how does it benefit society?
My current focus in science is predominantly in biology, with an emphasis on computational methods to model and analyze biological data. While I’m still learning and progressing through my bachelor’s, my goal is to enter research regarding biotechnology and sustainability, with an emphasis on communication and making science more accessible to policy-makers and the general public. Information is one of the most powerful and freeing tools we can have as people, and my work will encourage solutions to our rapidly expanding sustainability issues as well encourage more people to engage with science. My most recent work was centered around investigating the power insecurity in Puerto Rico as a result of the hurricanes across the last decade, including educating and communicating the geopolitical landscape and data through various presentations.

What is your favorite part about being a scientist, and how did you get interested in science?
I didn’t know what I wanted to do for the longest. I’ve had so many passions and was originally lined up to pursue a degree in the arts after winning an art award through the United States Congress. However, throughout secondary school, I was introduced to the concept of genetic modification and was completely fascinated by the potential of humans to understand and improve the world around us through genome editing. Soon after, I heard about the brand new Quantitative Bioscience program at Colorado School of Mines and just knew it was the perfect fit as I entered college.

As for my favorite part of being a scientist, it’s simply how what you learn begins to explain so much of the world around you. Whether it’s something as simple as the basics of plant growth or as complicated as the inner workings of recombinant DNA, all the information you learn helps you better engage with, understand, and appreciate the world around you.

“Fragmentum” – The award-winning piece mentioned, a self-portrait investigating identity and how we present ourselves to the world.

What advice do you have for up-and-coming scientists?
My best advice is to not be afraid of not knowing. So often I used to be scared of what people would think about me asking certain questions or I wouldn’t want to do things because I wasn’t fully comfortable. I wouldn’t ask questions in lecture or I wouldn’t take a guess if I was not totally certain. Asking questions and engaging with what is uncomfortable is some of the best ways to learn and develop your capabilities both as a scientist, but also as a person. In my own experience, I have learned so much more from situations where I was uncomfortable. Taking the time to talk to those who know more than you lets you learn, grow, and even build up your network. So, take that opportunity you’re unsure of, ask your “dumb” question, be unafraid!

 

 

Habiba Rabiu, Undergraduate

Fig 1: a selfie of me (Habiba)

My name is Habiba, and I am currently working on an environmental geosciences B.A. degree at Fort Hays State University. I was born and raised in Norfolk, Virginia, USA, but now live in Kano, Nigeria, where my family is originally from. Other than science, I love traveling, baking, and writing, but my number one hobby is reading! I read all genres and as much as I can. 

As a budding scientist, I am interested in specializing in environmental science and earth sciences such as geology and hydrology. My passion for science lies where those two fields intersect: climate change, conservation, and sustainability. 

I love science because I love solving mysteries and discovering new ones. My love for science is one of the oldest, most ingrained parts of my identity: both of parents are biology professors and made science and education a huge part of my life from the very beginning. Everything from astronomy to botany to engineering was discussed in our household, and trips to botanical gardens and various science museums make up some of my fondest childhood memories. I was taught from a very young age to admire and reflect on the marvels of the universe and everything that inhabits it, and that instilled an enthusiasm in me that never waned. I chose to focus on earth and environmental sciences as a career path because I believe it is where I can learn the most and make positive, truly impactful contributions.

My goal as a scientist is ultimately to learn as much as possible and share my knowledge with others. In my corner of the world, climate change and the exploitation of natural resources has left serious effects on the lives and livelihoods of the people here. I hope to do some work involving community outreach that will inform the public about the environment and educate them about what they can do to help preserve it. All over the world, more effort is needed to unite everyone in the goal of protecting and appreciating our planet, and I could not be more eager or ready to be a part of that!

I am still on the journey to becoming a scientist myself, but if I had any advice for someone who wanted to come along, it would be to seek as much knowledge as you can from everywhere possible. For every aspect of science there is an endless number of resources available to explore it. It is easy to get intimidated by technical language or imposing ideas but remember that all scientists have to start from somewhere, and when you do the only way to go is up! All you need is curiosity and determination.

I am currently a junior in college. I am a transfer student; this summer, I am getting ready to transfer to Augustana College  as a geology major from community college. While in community college, I published a couple of pieces in a literary magazine. The first is a creative work called Cole Hollow Road, and the other is a personal reflection piece called Est. 2001, Discovered 2021. Est. 2001, Discovered 2021 reflects on my mental health and growing into who I am. I work about 30 hours a week at a retail store called Blain’s Farm and Fleet. I have been working there since October of 2020. I work in Men’s Clothing, and I mainly sell denim jeans and work boots. With the little free time I have, I explore the outdoors with Noah, my boyfriend, work on my unpublished novel, The Gamemaker,  read books on science communication, and write articles while participating in the Time Scavengers VIP SciComm Internship.

What kind of scientist are you, and what do you do?
Since I am a junior in college, I am still figuring out what my role is within the scientific community. I love to read and write, and I aspire to be a science communicator, but I’m still figuring out what role best fits me. What I do know is there is a distinctive difference between an intelligent person and a good teacher, and I want to teach others about science in an engaging way. 

One of my favorite things about being a scientist is seeing so many cool rocks and learning their stories! I’ve been collecting rocks and fossils since I was seven or eight years old! I enjoy showing others what fossils I have bought or found and telling the stories that accompany them. I also love public speaking and can see myself being successful in either an in-person capacity or creating videos/content online. I also think being a tour guide or research scientist for a National Park would be awesome! I am looking forward to exploring my options as I continue my education. 

What is your favorite part about being a scientist, and how did you get interested in science?
My beginning journey into the scientific community is a little bit unusual. I was first introduced to fossils in a Worldview, Logic, and Apologetics class (which is about advocating for the Christian Faith). I worked on an extensive project that asked the students to study a field of science of their choice in order to find evidence in support of the Christian faith. It was a very intriguing and motivating project that has led me down a now six-year philosophical and scientific journey to figure out how these two pieces of my life, religion and science, can coexist. Because of this class, I wanted to be a geologist because I wanted to know as much about our origins as humans, but also what has happened to our planet in geologic time. I also want to know how to learn from nature about our history, but also what we can do to maximize our future. 

I grew up with a stigma that in order to be a scientist, you needed to be an expert in math, lab activities, and memorization. I grew up attending a college prep school where STEM majors usually were pre-med or engineer inclined. I knew I was not interested in studying those fields (even though they are awesome in their own right!), and felt it was hard to keep up with kids in my classes because my focus was different.  It was a very competitive environment, especially because I lacked confidence in my ability in the skills I thought were necessary. However, after learning what geology was about in college, I knew I had found my place. Geology integrated my love for weird creatures, writing, and being outside! Combined with my natural inclination to write, I quickly fell in love with the idea of becoming a science communicator.

The building behind her, on top of the stairs which climb the hill, is an old academic building with dolomite (a hard, sand-colored mineral) walls and arched windows.How does your work contribute to the betterment of society in general?
I once had a classmate tell me he used to be interested in paleontology, but they thought it was a “dead” science and became readily disinterested. The more I delved into the literature, the more I knew he was far from the truth! My goal as a scientist  is to advocate for the amazing things we can learn about our world through science (but especially paleontology!), and to hopefully encourage aspiring scientists that they can find their place in the scientific community. One way I have begun to do so is by starting my blog called Perusing the Primeval. My blog currently has a Book Review Section that includes the latest books in science communication. I have a review template that shares how technical the book is to help the reader get a sense for who the book’s intended audience is. There are a wide variety of books available, and my goal is to help someone looking for new recommendations to find something they will enjoy. I am currently working on a Species Spotlight section that will highlight a certain extinct species represented in the fossil record.

What advice do you have for up and coming scientists?
As I said before, I grew up in a competitive academic environment. I often felt like I was in academic “no man’s land”; I was bored in regular classes, but I was crawling to keep up in the advanced classes. I enjoyed school and wanted to challenge myself, so I was often comparing myself to kids who were more academically inclined in subjects that did not come naturally to me. I felt like I needed to compete against them in order to get a spot in a good college. Rather than focus on my strengths when applying to colleges, I pushed myself to do things I didn’t really like because I thought I needed to compete for my spot. I thought “being amazing at everything” was my ticket to a good school, but I found out very quickly that wasn’t true. If you are interested in going to college (or trade school or an apprenticeship), I would encourage you to lean on your strengths. If you have strong passions or interests, fuel the fire! Continue to hone in on those skills. If you aren’t quite sure of what you want, try different things and see what you like – but maybe not all at once. Your physical and mental health will thank you. If we as individuals were all “amazing” at everything, we wouldn’t need each other!

Person holding up a skeleton of a shark's mouth framing their face, smiling.Tell us a little bit about yourself. 
My name is Tessa Peixoto and when I was younger I was referred to as shark girl. I was super obsessed with sharks, which is what got me into science. Outside of science though I am a fan of doing art, specifically painting and building things, and I like baking for friends and family. Movies are a go to past time for me, and I am one of those people that really like b-rated sci fi movies. For instance, Tremors, highly suggest watching it. I am a science enthusiast so when I go out for walks on the beach, hikes in nature, or anywhere else I am still observing what kind of life I see. It is a way of connecting with the planet for me. However, my friends just give me a pat on the head when I yell excitedly about finding Codium fragile on the beach. One time, I found a carcass of a skate on a beach and I ran to anyone who saw me holding it so I could show them.

What do you do?
So I studied marine biology as an undergraduate student. During my studies and soon after I was able to conduct or participate in research on intertidal blue mussels, describing freshwater stingrays, and describing the morphology and function of the armor for a family of fish called Poachers. Soon after I was able to be a seasonal aide for the California Department of Fish and Wildlife and got exposed to doing trawling surveys in river tributaries.

Person on a boat with a bright orange life jacket on in the foreground, with calm lake waters in the background and a low mountain range in the distance. After graduating and my bopping around the US for a variety of temporary science positions, I found myself working as a museum educator. It was the funnest thing to be around so many specimens for every kind of field of natural sciences. Plus, I was able to use a lot of those specimens as part of my teaching practice during classes that field trips could sign up for. Unfortunately, as the position was part time, life demanded I find a position that could provide me benefits that would support me more efficiently. I now work as a science instructor for an Adult Education program in Boston, MA. It is truly a rewarding position because as I get to share my love and fascination of science with my students, I know I am helping them get closer to obtaining a high school diploma, which only improves their job prospects.

What is your favorite part about being a scientist, and how did you get interested in science?
When I was younger, I remember my brother was always doing something with his hands. I remember always seeing him carve up soap bars and for some reason I understood it to be science, or rather an experiment. I also was really into ocean documentaries, anything on Discovery Channel that highlighted the ocean or environment would be something I would pay attention to. And yes my attention was even more peaked if sharks were in it. At one point during our youth my brother told me that if I wanted to keep learning about sharks that I would have to be someone who studies marine biology. And thus began my stubborn journey in declaring I will become a marine biologist.

Fast forward to college, I entered Northeastern University to study marine science, as I had stated repeatedly since I was younger. Interestingly enough, the more science classes I took the more I realized I just liked science, all of it. It took a bit of time for my fisheries teacher to get me to let go of my stubborn obsession with sharks, but I would say once I did, my understanding of marine biology as a whole was improved. Bachelors of science is where my formal education ends, therefore I have not yet become a marine biologist. Nevertheless, my enthusiasm for science has not dwindled away. It is still very present and of course with a slight favoring of anything ocean.

I have enjoyed the opportunities I had in college and since college because I kept getting to learn from the people around me. Especially, in the two science conferences I participated in. I love being able to see other people’s posters and discuss with them their thoughts and their research.

Person wearing a black jacket and black pants in a poster hall, standing in front of a poster with scientific results. How does your work contribute to the betterment of society? 
As much as I did not for-see myself as being an educator, I am happy I am in it. Mainly for the reason that I can finally share science with adults that avoid science because they had horrible experiences from their last time in education or didn’t really get a chance to do formal education in their youth. So when I teach I aim to be open and caring of their learning journey, and to never dismiss their questions. It benefits society as they become great learners and more confident in their skills. Being an adult educator is very important  because it can help disseminate science in a way that helps the world presently. Essentially, I work with individuals that have the current and immediate ability to be stewards of the planet as their understanding of the world improves. As much as education of children is very much needed, I want to improve the science literacy of the adult population. A future goal of mine is to help increase options that are free, supportive, and open to questions that adults have about science, and the inner workings of the planet.

Person standing on a dirt path, in the woods, with thin trees behind them, low shrubs in the foreground. Person is looking up towards the sky. What advice do you have for up and coming scientists and educators?
Something I want everyone to know is to not judge yourself on your performance in classes. Just because you might have gotten a lower grade in a science class does not mean you would be a bad scientist. I also want to say the science or career you might think you want to do might be a completely different field of science or career by the time you graduate, finish a PhD or look for private corporation positions. If you are reading this as someone in high school or college, try out different internships. I know when I was younger I would only look for internships with sharks, and that stubbornness sometimes prevented me from just learning about different fields. Therefore be open to options that come your way. If you are reading this as someone that is mid career, I would say to talk to people in the field that you are interested in. Find others interested in a similar field and hang out with them. For example, there are many groups of mycology fans that meet up every now and then to go foraging and talk mycology. Science in its purest form is about curiosity and asking questions, so keep asking questions and explore our wonderful world.

What is something exciting you are doing at the moment?
I currently am the outreach officer for the JOIDES Resolution that falls under the International Ocean Discovery Program (IODP). This position provides a great view into the world of science communication that is different from the that of the communication done in a formal education position. The outreach officer has the chance to reach out to anyone in the world and share the life of living on the ship and doing research on the ship. This is just a temporary position for the summer, but offer the chance to learn about geosciences, and other ways to explore the Earth. If you are reading this know that you can call into the ship during an expedition and get a tour of your own, it might not be with me but it will be an outreach officer that has the same excitement as I do.

I am a marine geophysicist that studies crustal structure. I use techniques that allow us to image the subsurface to study topics such as how ocean crust is formed or what an impact crater looks like in three dimensions. My favorite instruments are ocean bottom seismometers – we drop these off the side of a ship and they record sound waves that travel through the earth. Later we send a signal to each instrument and it lifts off the seafloor for recovery.

I was part of a team that acquired site survey data in the South Atlantic for IODP expeditions 390 and 393. These data allowed us to choose the best sites to recover both sediments and basement rocks. It is very exciting to see the drill cores from the sites we picked! The cores provide the ground-truth that allows us to better interpret our geophysical data over the South Atlantic region.

A previous project I was involved in was studying the Chicxulub impact crater which formed 66 million years ago when a meteorite struck at the Yucatan Peninsula in Mexico; effects from the impact led to the extinction of the dinosaurs. When I first started out as a research scientist I was part of a team that acquired geophysical data over the Chicxulub structure and confirmed that it was an impact crater. More recently I was in the scientific party that drilled into the structure and recovered rocks from the impact crater!

Growing up I was always interested in science but didn’t know much about earth science. In high school I received information about applying for a scholarship to study geophysics – which I learned was studying the physics of the earth. Once I took my first geophysics course and discovered plate tectonics I was hooked! After graduate school I became a research scientist at the University of Texas Institute for Geophysics (UTIG) where I worked for almost 28 years. I recently took a position as a Program Director at the National Science Foundation in the marine geology and geophysics program. I now get to manage the review process for proposals to conduct cool science all over the world’s oceans!

My biggest hobby is soccer. I love going to see Austin’s new soccer team Austin FC, and my favorite way to spend a Saturday morning is to grab a breakfast taco and watch Premier League soccer matches. I also enjoy reading science fiction and fantasy and watching movies.

I’m Jeff Ryan, a Professor of Geology in the University of South Florida’s School of Geoscience.  On IODP Expedition 393, I’ll be sailing as an Inorganic Geochemist.  It’s my third IODP research drilling cruise, all sailing this role.

In terms of geology subspecialty I’m a “hard-rock” geologist, as I mostly work on igneous and metamorphic rocks.  My research primarily focuses on subduction zones, where Earth’s tectonic plates head down deep-sea trenches and cycle back deep into the Earth’s mantle. I study subduction chemically, using key trace elements and isotopic ratios to understand how the old, cold, wet ocean crust reaching deep sea trenches changes as it subducts, and how fluids and melts driven off subducting plates change nearby mantle rocks and lead to volcanism at island arcs, and even at oceanic hotspots like Hawaii or Iceland.  My interest in Expeditions 390-393, which will drill sites in the south Atlantic, nowhere near a subduction zone (!!), is to better understand how the composition of ocean crust changes as it ages, and so what the differences are between the young seafloor subducting beneath the Cascades, and the very old crust going down beneath the Lesser Antilles, or the Mariana Islands in the Pacific.

In my courses at USF I use the ocean drilling research I’m doing directly in teaching our Geology students. My Junior-level Mineralogy/Petrology course has for the past six years examined unusual volcanic rocks from the Izu-Bonin subduction zone that I helped recover as a Shipboard Scientist on IODP Expedition 352.  The students made some very cool discoveries about the minerals and textures in those samples, which led to a recent student-authored scientific paper in the journal American Mineralogist (Scholpp et al 2022).   I hope to do something similar for my future students with Expedition 390-393 basaltic samples.

People come to geology a bunch of different ways, I’ve found.  In my case it was a childhood interest in rocks and minerals, combined with a penchant for creative writing.  Geology is at its core a storytelling science: we divine and tell the “stories” behind the places in the Earth that we examine.  When I encountered the science fully for the first time, as a Freshman in my first undergraduate college course at Western Carolina University, it was a perfect fit.  I’m looking forward to helping tell the story of how the south Atlantic Ocean crust formed and evolved as part of IODP Expedition 393.

Colin Boisvert, Paleontologist (in training)

Describe your hobbies and interests outside of science. I am an avid reader both in non fiction related to paleontology, evolutionary biology, a lot of different scientific subjects in general and fantasy, science fiction and some other fiction. A few of my favorite authors include Pierce Brown, Christopher Paolini, Edgar Rice Burroughs, and Frank Herbert. I am also a huge nerd when it comes to a lot of popular media franchises such as Star Wars, Indiana Jones, Jurassic Park, Lord of the Rings, Harry Potter, MCU, DCU and  Ghostbusters to name a few and quote movie lines all the time. I am a big costumer and have built my own Mandalorian armor among other costumes such as  the First Avenger Captain America  and Obi Wan Kenobi. I love to hike with friends, swim, and travel to new places (especially those with paleo stops).  I love spending time with my family and friends and am a big foodie.

Discuss anything else about yourself that you’d like to share that doesn’t have to do with your career. I grew up in the Silicon Valley in Northern California which shaped my love for paleontology and my love of some of my hobbies. I spent a lot of time outside, especially as my Grandparents moved when I was younger to the Santa Cruz Mountains where I fell in love with the forests there. Much of my family lives in Northern California and I have remained close with all of them.  I love meeting new people, especially other scientists! 

What is your role? I am a Vertebrate Paleontology Graduate Student working towards my Masters in Geology focused on Vertebrate Paleontology at BYU. Currently that just makes me a Mr. Boisvert but working towards eventually becoming Dr. Boisvert! I am currently working with Sauropods and specifically the neck biomechanics of Apatosaurus excelsus to understand more about how this animal held its neck and what the species’s possible feeding envelope was.

Do you conduct outreach? I would love to get into more outreach with school age kids here in Utah. I was an education intern this past summer at the Mammoth site in Hot Springs, South Dakota and loved it! However nothing is set up at the moment, so the only science outreach I communicate on is with my fossil Friday posts!

The BYU Museum of Paleontology recently had professional shots done with photographers from campus using some of the specimens on display. This is a favorite shot of mine illustrating a pose similar to the classic Alas poor Yorik pose from Shakespeare with a cast of the skull of Big Al ( famous specimen of Allosaurus jimmadseni). While I do love studying sauropods, Allosauroids will always have a special place in my heart.

What is your favorite part about being a scientist, and how did you get interested in science? My favorite part of being a scientist is getting to work to uncover the past every day and sharing my discoveries with people.  I get some of the greatest joy when I get to give tours or share what I have learned about prehistory and learning that while doing research is an equally amazing feeling. Having conversations about current topics in the field of paleontology is an exciting prospect that I always look forward to at conferences or over zoom. I became interested in paleontology at a young age, took earth science, biology, and chemistry in high school. From high school, I attended UC Davis where I did a double major in biology and geology. I had a status year where I was a tutor and then worked as a Mammoth Site Intern in the summer of 2021 and since August of 2021 have been working on my Masters at  Brigham Young University.

Besides paleontology, I love learning more about geology, evolutionary biology, phylogenetics and biogeography in general. I also enjoy learning more  about the history of different sciences including paleontology, geology, and the theory of evolution. Besides my project I would love to tackle scientific questions relating to the Mid-Cretaceous Sauropod Hiatus where we don’t see Sauropods in North America and Europe for between 25-30 million years in the fossil record.  I would love to help close the gap between the transition of Dinosaur fauna in Western North America between 95-80 million years ago as well as what dinosaurs lived in Appalachia, the Eastern half of  North America. Finally it would be interesting to test comparisons between famous North American faunas like that at La Brea Tar Pits vs the Morrison Formation and what similarities in ecological roles there are between the two ecosystems.

How does your work contribute to the understanding of evolution and paleontology? My work contributes to paleontology through how this research with Apatosaurus can help us more with understanding this sauropod’s neck posture and range of motion. By understanding how this animal moved and what it fed on, we can better understand the Morrison environment in one small aspect. At the time of my specimen, we have 5-7 large coeval sauropod species and by understanding the diet of this species we can begin to piece together the puzzle of how all these animals were able to coexist. The specimen I am studying is unique as it does not suffer from several of the problems plaguing sauropod neck studies such as bone distortion and incompleteness of specimens.

How does your outreach contribute to or benefit society? Fossil Friday posts such as mine  are important for helping to engage those connected to scientists through social media, spreading information about unique species, specimens and collections that  are out there and providing recognition of the work that is done in our field and localities people should visit. A smile put on someone’s face learning about the past today, can inspire a budding scientist for tomorrow.

What advice do you have for up and coming scientists? Science is rough and not always a 9-5 job. It may require early mornings/late nights but the work is worth it and there is such an amazing feeling you get when you can present research at a conference and talk with colleagues about what you are studying. I wish I had known that jobs are difficult to come by as are graduate student positions so working really hard helps with being more competitive when applying to positions. Reading scientific papers is important for developing a good understanding and field vocabulary.

Have you received a piece of advice from your friends, mentors, or advisors that has helped you navigate your career? Looking for a variety of programs can help with applying to graduate school, publishing is very important and problem solving is key for scientists. I also learned two key tips for investigating possible graduate programs. 1, it is very important that you and a possible adviser can get along and will you get along if you attended there. 2, are they studying similar organisms/using techniques you wish to learn about so they can help you more when you have trouble with projects.  Making an attempt to establish contact with a potential advisor before applying is a great way to build a relationship with them and can help with your application. It can be as simple as having a zoom meeting to discuss their research lab and interests.
