David L. Freedman is a professor and Chair of the Department of Environmental Engineering and Earth Sciences at Clemson University. David’s academic journey started at UWGB in 1973, when he made the move from his hometown of Worcester, Massachusetts to Green Bay to join many other undergraduates from across the U.S. who shared a deep concern for the fate of the planet. David earned a B.S. degree in Science and Environmental Change in 1978. Among his many experiences at UWGB, one that stands out is his participation in a project to build a pilot-scale anaerobic digester on a dairy farm, one of the first to be built in Wisconsin. The project was unusual because it was a student led effort, from design to construction to operation. David was part of the project from start to finish, culminating in successful demonstration of a technology that has now been widely adopted.
