B.S., University of Washington - Tacoma, Environmental Science, 2008
I grew up in a small town in southwest Missouri. I received my BS in Environmental Science from University of Washington-Tacoma, with a thesis project focused on marine larval ecology. I earned my PhD from Iowa State University with co-majors in Ecology and Evolutionary Biology (EEB), and Environmental Science (ENVS). My dissertation research focused on plant communities at regional to sub-continental scales and how they have interacted with climate over geologic time. I completed a postdoctoral fellowship in the IRACDA@UCLA faculty training program, and am a UCLA Center for Diverse Leadership in Science Early Career Fellow. My postdoctoral research involved improving statistical and methodological techniques for the calibration of paleoclimate signals, and writing open-source software to allow for community-wide implementation of reproducible statistical methods in clumped isotope paleothermometry.
I am passionate about undergraduate and graduate science education, and my teaching interests center around evidence-based teaching methods aimed at promoting equity and inclusion in STEM.
What most excites you about your field?
Studying the ecology and climate of the past is exciting, because it’s the closest we can get to having a time machine. I enjoy trying to piece together clues left behind by ancient organisms to better understand what happened thousands or tens of thousands of years ago. It gives us context for what we are experiencing now, and what we will experience in the future as our climate continues to change.
What is your favorite thing about the Gunnison Valley?
I love the rugged beauty of the Gunnison Valley
