Before starting at Cornell in 2014, he completed his Masters at the University of Alaska, PhD at Cornell and a postdoc at the University of Massachusetts-Amherst. Major current research projects include: 1) Assessing pesticide risk to bees across different landscape and agricultural contexts, 2) Evaluating the relative importance of pesticides, pathogens and other factors on colony performance, and 3) Understanding pathogen transmission in complex plant-pollinator networks. Current extension efforts include the NYS beekeeper tech team, training veterinarians on honey bee diseases as part of the new Veterinary Feed Directive and advising growers on pest control practices that minimize risk to bees.
