The principal focus of my research program is the consequences of life history and environmental change on nutrition. I work with other scientsists and students to study ungulates (e.g., reindeer, caribou and muskoxen) and waterfowl (e.g., ducks and geese) as well as non-game species (e.g. porcupines) in both wild and captive populations.
