Peter Larsen

Assistant Professor

Veterinary and Biomedical Sciences

Larsen focuses on investigating host-pathogen interactions. He is an accomplished genomicist with research interests in the genetics of stress, emerging pathogens, and the origin of neurodegenerative disease. Larsen’s program will use cutting-edge genomic technologies to advance several lines of food animal research. Initial projects in his lab will focus on the epigenetics of stress in dairy cattle and the utility of portable, hand-held DNA sequencing technology for real-time food animal diagnostics. He has spent the past six years at Duke University where his research resulted in a new model for the origin of Alzheimer’s disease. Prior to his time at Duke, Larsen spent a year with the USDA in Clay Center, Nebraska where he conducted research on antibody variation in beef cattle. Larsen earned his Ph.D from Texas Tech University.
