My approach to sustainability science, practice and teaching is informed by my training in ecology and conservation biology. My research broadly focuses on ecosystem function, resilience and recovery, and combines long-term observations from field studies with experimental manipulations and multivariate analyses of change. Wherever possible I strive to integrate research training, field techniques and laboratory methods into my coursework, with the goal of providing students with the skills and experience necessary to pursue meaningful careers in science.

I was previously faculty of biology at Boston University, and field program lead with the BU Marine Semester. I have taught courses at Tufts University, Wellesley College, the University of Alaska Fairbanks, Columbia University’s Earth Semester, and the University of Arizona’s Nyanza Project, Tanzania (National Science Foundation Research Experiences for Undergraduates). I am delighted to join the faculty in the Bachelors of Arts in Sustainability Studies Program here at Colorado Mountain College.

Rocky Mountain Land Management Internship

I currently serve as Program Lead 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 and social resource specialists, and forest rangers. Learn more about the Rocky Mountain Land Management Internship Program.
