Promoting Geoscience Research, Education & Success

My interests

My research interests lie in generating Holocene paleoclimate reconstructions in the Canadian Arctic. I focus on two main tools for generating these records: dating glacier moraines using cosmogenic radionuclides, and analyzing multiple climate proxies contained in lake sediment cores. I’m also very interested in K-12 geoscience education and volunteer in the community through multiple organizations. When not in the lab or the field, I love getting outside—trail running, cycling, hiking, skiing, and anything else that gets me out enjoying Boulder’s beautiful backyard.

How I became a scientist

When I was in high school, science was my least favorite subject; I found the rote memorization to be boring and uninspiring. Fortunately, my freshman year of college I took a field-based geology course that opened my eyes to the dynamic nature of scientific inquiry and showed me how engaging learning about the landscapes around me can be. I was hooked. I completed my Bachelor’s degree in geology, which included a senior thesis on crustal block rotation near the San Andreas fault, along with a concentration in environmental studies. After a few years away from academia, I decided to pursue a graduate degree that was focused on paleoclimate, as it combined my academic interests in the geosciences with my motivation to contribute to our understanding of modern climate change.

How my work benefits society

Paleoclimate reconstructions are important for creating a baseline to which we can compare modern climate change, particularly in the climatically sensitive Arctic. Insights into how glaciers and other parts of the Earth system have responded to past change can also give us a better idea of how they might be modified due to anthropogenic change. I do my best to communicate what we learn in the Canadian Arctic through K-12 outreach and to the general public so that our work can have impacts beyond academia.
