Mark Hanigan is the David R. and Margaret Lincicome Professor of Agriculture at Virginia Tech. He earned his Ph.D. in Nutrition from the University of California, Davis, following a B.S. in Dairy Science from Iowa State University, and completed postdoctoral work in biochemistry at UC-Davis. His research focuses on amino acid metabolism, protein deposition, and nutrient utilization in lactating dairy cows, particularly the effects of rumen-protected amino acid supplementation and dietary protein restriction on nitrogen balance and milk production. His recent work includes meta-analyses of postruminal amino acid outflows and investigations into gastrointestinal permeability and heat stress responses. He collaborates extensively with institutions across North America, Europe, Asia, and Oceania.
