As a paleontologist I study how fossils are preserved in the fossil record (taphonomy), and how morphology changes within species across space (geographically) and through time (stratigraphically) in response to several processes such as ontogeny (development) and environmental change.
As a Curator in a museum, I use my research to teach our community about the process of science and why paleontology and geology are important to our society today. I am also very passionate about public science literacy, and am involved in educational program and exhibit development as well as lecturing on a variety of science topics in geology and paleontology.
My research is specimen-based, and requires a lot of intensive fieldwork. This is fantastic for me, because I love to be outside and being active. I get all of the trilobite specimens for analysis by hammering them out of the rock layers. I then bring them back to the laboratory where I prepare them out of the rock, photograph and measure them, and then conduct my mathematical modeling and statistical analyses to test my hypotheses and answer my questions (while generating new ones!).
Understanding the biotic response to climate change is crucial for our society, especially in the face of our current climate crisis, but modern biological studies are not long enough to document the long-term impact of these changes. The fossil record is an excellent resource to study species’ response to environmental change over the long term because it shows us the consequences of previously run climate change “experiments” in Earth’s history. My research shows that trilobite populations can track their preferred environment over millions of years and through constant climate perturbations rather than evolve new adaptations or go extinct. This response is consistent with many other examples in the fossil record and shows us that migration is a viable and successful response to climate change for many species.
My favorite thing about being a paleontologist is that it is the closest thing to time travel that we have. When I am in the field, I am looking at fossils that take me back 450 million years in Earth’s history, and I am usually the first person ever on Earth to have seen and collect these fossils. The fact that I am traipsing around an ancient ocean that once covered most of the United States still blows my mind. As a scientist in a museum, I also enjoy teaching the public about the amazing planet we have and the relevance, to their lives, of the world-famous paleontological resources in their back yard. There is nothing more rewarding than a child in awe.
Whatever path your career takes you on, be passionate about it. Whether you want to be a paleontologist, another type of scientist, or pursue a non-science career, if you are passionate about what you do, you will never feel like you are going to work. I look forward to what every day brings because every day is different.
