What I do

I teach a wide range of courses in ecology and biology.  My research focuses on the phenological responses of plants and animals to climate-driven environmental change including the synchrony of migratory birds with their habitat and the impacts of changing snowpack and snowmelt timing on moutain ecosystems.  I am also involved in sustainability issues, non-motorized recreational trail development, and human and public health.
