Assistant Professor



The Milbrath lab studies risk factors that affect the health of honey bees and other pollinators. We focus on a combination of field, lab, and computational work to answer questions related to pollinator health.

Current Assignment: Teaching 10% | Research 45% | Extension 45%


My current teaching program consists of the three week rotation for veterinary students in honey bee medicine.
My program is focused on using an interdisciplinary approach, rooted in epidemiology and environmental health and risk assessment, to understand risks to pollinator health, especially during crop pollination. We examine how nutrition and pesticide exposure affect disease development and colony health outcomes in honey bees, as well as basic research into common honey bee pests and pathogens.
