Research Assistant Professor



My research program is centered on developing fungal based biological control agents for arthropod pests. Microbial based biopesticides can decrease agricultural chemical inputs into our food supply and are considered to be inherently less risky to humans and other vertebrates compared to traditional synthetic chemical pesticides. Biopesticides, however, are susceptible to a variety of abiotic factors including temperature, humidity, and UV. My current research is focused on developing fungal based solutions to honey bee health, specifically breeding a fungal biopesticide to control the Varroa mite and exploring fungal and botanical based solutions to honey bee nutrition and overall health.
