We mourn the death of Thomas Simon, scientist and beloved SPEA professor. His work had a profound impact on our campus and on hundreds of our students. With a ready smile and always upbeat nature, he was a colleague treasured by our faculty and staff. Simon was an ichthyologist with over 35 years of experience working with complex environmental ecosystem issues and evaluating anthropogenic impacts on aquatic assemblages. He worked for the U.S. Fish and Wildlife Service and the Environmental Protection Agency in addition to teaching at SPEA for many years as an adjunct professor.
