Katie Schulz

M.S. student (co-advised with Laura Kenefic)

My study aims to understand of how partial harvesting impacts the structure, composition, and associated environmental conditions of lowland northern white-cedar stands. However, because future climate change conditions are expected to increase the frequency and intensity of droughts, my study will also determine how a range of environmental conditions (brought on by drought stress) impacts the growth, survival, and physiology of cedar and one of its main competitors, balsam fir regeneration.


Alexandra Barry

M.S. student

I am interested in using physiological and ecological perspectives to predict how forest systems in the northeastern US will respond to climate change-related disturbances. I am also interested in how various tree species resist the effects of extreme climate conditions, and what this might mean for future conservation and management practices.


Peter Breigenzer

M.S. student

Climate change poses serious risks to forest health and complicates the future of managing for multiple use. I want to strengthen my knowledge of tree ecophysiology and forest management in order to improve silvicultural techniques and practices.
