Research

I study physiological plant ecology, focusing on (1) herbivore-plant-microbe interactions ,  (2) physiological and growth responses to herbivory and  (3)  adaptation to, or effects of, environmental stress, primarily heat and sodium.  I am interested in elucidating species level adaptations to stress and herbivory that explain observed community dynamics (e.g. species distributions, competitive interactions,  and nutrient cycling) as well as relating adaptations to ecosystem function. The majority of my current research is based on large ungulate grazers (e.g. bison and elk) and their interactions with grasses and soil microbes in Yellowstone National Park (PHOTOS and BLOG).
