Research Focus: Effects of soil fumigation on hemipteran pests of potato.
Start Date: Summer 2020

Immediately after completing my bachelor’s degree in 2019, I began working at a biological control distributor. Here, I developed an interest in crop protection from arthropod pests and diseases. In developing biological control programs, the importance of integrating other methods that slow the population growth of pests became clear. This sparked my interest in the interactions between pests, their host plants, natural enemies, and the environment. My goal with the plant health master’s program is to be able to approach plant health-related problems with a broader and deeper understanding of the whole system.


The BPP program is currently providing weekly mummy berry updates to blueberry growers in western Washington. These weekly updates provide information on the timing of apothecia development from mummified overwintering berries so growers can time disease management practices accordingly.
