Peter Calow is research professor in the Office of Research at the University of Nebraska-Lincoln with specific interests in science and public policy. Before joining UNL in 2011, he spent most of his career in Europe as a professor at the University of Sheffield UK, where he developed programs in ecological risk assessment. He was an adviser to the UK government and the European Commission on industrial and agrichemicals in the environment. He was also director of the Danish government’s Environmental Assessment Institute, where he developed a keen interest in combining environmental assessment with cost-benefit analyses to develop policies that made sense economically as well as ecologically. He continues this work at UNL across a number of areas involving agriculture, energy, and water.
