I am a PhD student in the Plant Pathology Department. My research is on native forest pathogens of old-growth mixed-conifer forests in the Sierra Nevada.  I am interested in understanding how pathogens interact and impact natural forest systems by altering species composition, stand structure, diversity, and regeneration.  I am also interested in fungal biology, ecology, and systematics.

I joined the Rizzo lab in 2010, first doing fieldwork on Sudden Oak Death in Big Sur, CA, followed by a lab technician position working on stream monitoring for Phytophthora ramorum across its range in CA.
