William K. Hallman is a professor and Chair of the Department of Human Ecology and is a member of the graduate faculty of the Department of Nutritional Sciences, and of the Bloustein School of Planning and Public Policy at Rutgers, the State University of New Jersey. He is a 1983 graduate of Juniata College in Huntingdon, Pennsylvania and earned his PhD. in Experimental Psychology from the University of South Carolina in 1989. Dr. Hallman’s research examines public perceptions of controversial issues concerning food, health, and the environment. Recent research projects have looked at consumer perceptions and behaviors concerning genetically modified foods, animal cloning, avian influenza, accidental and intentional food contamination incidents, and food recalls. His current research projects include studies of public perceptions and responses to food safety risks, the safety of fresh meat, poultry, game, and seafood products purchased on the Internet, the use of nanotechnology in food, and public understanding of health claims made for food products. Dr. Hallman serves on the Executive Committee of Rutgers Against Hunger (RAH), and helped to found the New Brunswick Community Farmers Market, which offers food insecure residents access to fresh, locally grown, affordable, nutritious, and culturally appropriate produce and other food products. Dr. Hallman formerly served as the Director of the Food Policy Institute (FPI) at Rutgers, and currently serves as the Chair of the Risk Communication Advisory Committee of the US Food and Drug Administration (FDA).
