My research focuses on ecology, epidemiology, and physiology. I am specifically interested in the connections among environmental conditions, key traits of hosts and parasites, and disease dynamics in natural populations and communities. In particular, I am fascinated by factors that drive variation in parasite transmission and reproduction. My approach to science combines field surveys, experiments, and mathematical models. During my dissertation, I linked pollutants, nutrients, and host density to the magnitude and severity of fungal outbreaks in populations of the planktonic grazer, Daphnia dentifera. I am now shifting my focus to the human zoonotic parasites, Schistosoma spp., and their intermediate snail hosts. I am interested in building and testing body size- and resource- explicit models for Schistosoma epidemiology.
