Research Interests

I am a wildlife ecologist interested in abiotic and biotic forces that shape population and community dynamics of boreal and subboreal species along distributional edges. Through camera trapping, snow tracking, pellet count surveys, and occupancy and density modeling, I partnered with NH Fish and Game, VT Fish and Wildlife, US Forest Service, and US Fish and Wildlife Service to take a landscape approach to study the impacts of climate and forest dynamics on montane wildlife.
