Research Interests

My research interests lie in the unique and often neglected milieu of phylloplane (leaf surface) microbial ecology.  I am interested in understanding the roles that interspecific interactions, anthropogenic disturbances, and climate play in producing discernable patterns of species diversity and community composition in phylloplane fungal communities.  Testing existing theories in sessile, multi-species microbial communities allows me to assess and explore ecological theory in a manner that is often difficult or impossible to do with higher organisms.  Additional interests include investigating the resilience of phylloplane fungi to climate change and disturbance; determining whether changes in environmental parameters increase vulnerability of plants to disease due to alteration of the phylloplane mycoflora; and uncovering how phylloplane microbes alter their environment as a result of natural and anthropogenic pressures.
