About

My approach to teaching ecosystem science and sustainability are informed by my training in ecology, conservation biology, and quantitative research in coupled human-natural systems. My research broadly focuses on ecosystem function, resilience, and restoration, and combines long-term observations from field studies with experimental manipulations, remote sensing, and multivariate analyses of change. My courses strive to integrate diverse ways of knowing nature and traditional ecological knowledge, and prioritize research training, field techniques, and laboratory methods with the goal of providing students with the skills and experience necessary to pursue meaningful careers in community-engaged science, natural resource stewardship, and natural climate solutions.

I am a co-founder of the Yampa Basin Rendezvous (hyperlink), a partnership and annual conference focusing on western water, weather, climate, and community resilience. I serve as an undergraduate summer research mentor with the Center for Western Weather and Water Extremes (CW3E), Scripps Institution, UC San Diego and represent Colorado Mountain College on the Y-BASIN climate monitoring network. I am also a member of the Lands and Water Technical Working Group, Routt County Climate Action Plan (CAP).

I was previously faculty of biology at Boston University, and field program lead with the BU Marine Semester. My prior appointments at Wellesley College, Tufts University, Columbia University’s Earth Semester, the University of Arizona’s Nyanza Project, Tanzania (National Science Foundation Research Experiences for Undergraduates), and the University of Alaska Fairbanks, inform my approaches to teaching in our Bachelor of Arts in Sustainability (BA.SS) and Bachelor of Science in Ecosystem Science and Stewardship (BS.ESS) here at Colorado Mountain College.

Rocky Mountain Land Management Internship

I serve as Program Director for the Rocky Mountain Land Management Internship Program, a rigorous field-based internship offered in collaboration with the U.S. Forest Service. This first-of-its-kind in the nation, two-year paid internship is designed to train the next generation of land managers, natural resource specialists, and mountain sports rangers. Learn more about the Rocky Mountain Land Management Internship Program.
