We’re kicking off the new year—and our new season of Dairy Digressions—with a special guest, Pete Hansen, PhD, Distinguished Professor of Animal Sciences and L. E. “Red” Larson Professor at the University of Florida. Pete’s research focuses on embryo physiology and developing new management strategies for increasing dairy cattle fertility, particularly in the face of heat stress and a warming climate. A leader in embryology and early embryonic loss, Pete explains when embryos are most sensitive to heat stress and why—including the scientific tools we have for preventing these effects—from genetic selection to embryo transfer to management for cow health and the potential future of artificial embryos from stem cells. A longtime mentor to undergraduate and graduate students (don’t miss his paper on the topic!), Pete also lets listeners in on his teaching philosophy and shares tips for crafting a lab environment that fosters collaboration, hard work, and joy around science.
