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. We have field sites in Maryland and North-Western Italy.

Fieldwork in Beltsville, Maryland

We have been working at the University of Maryland Agriculture Experiment Station (MAES) in Beltsville the past two years, studying phenology, fitness, and susceptibility of Silene latifolia at different ages to Anther-smut.

The Western Italian Alps are home to several anther-smut species (and their hosts). 

We made it out to Italy for a brief period in July to check in on a long-term implant experiment with Dianthus pavonius and make collections for our joint project with Michael Hood's lab on Silene vulgaris.
