Professor Peter Hansen is currently an animal science professor at the University of Florida. He has spent most of his career focused on the biology of pregnancy and embryonic survival, in order to use that information to develop approaches to improve fertility in livestock, especially dairy cattle. In addition to developing novel strategies for improving pregnancy success during heat stress in dairy cattle, Hansen has made major findings about the immunological relationship between an embryo and its mother. Hansen has conducted research into creating a more efficient reproductive cycle in cows during the summer months, when heat stress takes a staggering toll on successful pregnancies. Hansen has been awarded multiple times for his research, as well as his ability to work with training the next generation.
