Jeremy C. Andersen

Research Assistant Professor


Office: Room 307 Ag. Engineering


I am a Research Assistant Professor interested in using molecular methods to inform the study invasive insects and weeds, more successfully implement biological control programs, and inform insect conservation efforts.

Primary Interests

Population Genomics, Biological Control, Insect Conservation

Current Projects

Genetics of hybridizing invasive winter moth and native Bruce spanworm populations; Biological control of Japanese Knotweed; Identification of fungal pathogens of Hemlock Woolly Adelgid; Conservation genetics of endangered fireflies and bumble bees; Machine Learning to rapidly identify invasive species
