My research examines the causes and consequences of patterns in freshwater nutrient availability. Drawing from the fields of ecological stoichiometry, biogeochemistry, and disease ecology, I examine how traits of organisms respond to and shape the nutrient dynamics around them. Parasites are fascinating study subjects for this because their life history traits are relatively flexible, and they can exert strong effects on the life history traits of their hosts. My research detangles the complex interplay between parasites, their hosts, and nutrients using a combination of experiments and field studies.

Predicting the effects of nutrient inputs from humans on this interplay is a pressing issue. I work to mitigate negative anthropogenic effects on freshwater nutrient availability by studying the effects of infrastructure and land use on freshwater ecosystems across multiple spatial scales.
