Research interests

I am broadly interested in how anthropogenic drivers alter the abundance and diversity of parasites. We live in an era of rapid global environmental change, biodiversity loss, species introductions, and emerging infectious diseases. Understanding relationships among these processes is critical for limiting their impacts on food production, ecological resilience, and human wellbeing. Yet, doing so is complicated by the fact that these processes occur across spatial and temporal scales. I take a complementary approach to address this challenge, using experiments, large-scale field surveys, and data syntheses across a variety of study systems, so that we can better understand and predict infectious disease risk in our changing world.
