My long term research interests are to understand how selective pressures affect  symbiotic microbial genome content and how population diversity reflects natural history of these processes. This innate curiosity has driven my scientific exploration of plant associated fungi, bacterial-fungal interactions, and human pathogenic fungal interactions. I use genomics in these systems to probe how fungal symbioses are established and maintained over time.
