Research Interests

Infectious diseases are more prevalent in some places, some times, and some host lineages than in others. What are the evolutionary and ecological forces that explain this variation? My research program takes on this big question by testing the contribution of specific factors, like parasite adaptation, host resistance, migration, and genetic diversity, to variation in disease prevalence and transmission. I’m also interested in other big problems in the evolutionary ecology of disease, including 1) the maintenance of sex by coevolving parasites and 2) the evolution of parasite virulence. I tackle these problems using a combination of long-term field data, experimental manipulation of field populations, and experimental evolution.  In most of my work, I now use Caenorhabditis nematodes (including C. elegans) and their natural parasites, which allow for targeted tests of foundational theory.
