We study the ecological and evolutionary dynamics of infectious disease in natural populations. Research in the lab is focused on understanding the impact of infectious disease on host abundance and distribution in natural populations, and how these ecological effects intersect with the evolution of important host and pathogen traits such as transmission and resistance. We use plants and their fungal pathogens as powerful model systems for investigating these questions.
