Research Interests

My research interests are in infectious disease microbiology, particularly fungal/eukaryotic pathogens of humans and animals. Analyses use techniques in molecular and cellular biology and genomics. Current projects focus on Candida species, Malassezia species, emerging fungal pathogens of reptiles, and the oomycete pathogen Pythium insidiosum.
