Jennifer Van Os is an Assistant Professor and Extension Specialist in Animal Welfare on the faculty of the Department of Animal and Dairy Sciences at the University of Wisconsin-Madison. Dr. Van Os received her PhD in the interdisciplinary Animal Behavior graduate program at the University of California-Davis and conducted postdoctoral research in the Animal Welfare Program at the University of British Columbia. The research in her lab at UW-Madison focuses on understanding, evaluating, and improving the welfare of dairy animals from biological- and social-science perspectives. The goal of Dr. Van Os’ extension program is to promote best practices in management and housing to help the dairy industry adapt as our scientific knowledge about animal welfare continues to grow.
