Research Interests

My research focuses on the ecology, chemistry, and physiology of plants and herbivores. I am particularly interested in the nutritional ecology of large herbivores in northern ecosystems, including moose, caribou, and black-tailed deer. To understand how habitats and plant communities influence the survival and productivity of these animals, my research explores a diversity of topics. These include studies of nutritional qualities of plants, plant defensive chemistry, plant architecture and its influence on foraging behavior and food intake rate of herbivores, the digestive physiology of herbivores, foraging behavior, and biological simulation modeling.
