Steven Safferman

Dr. Safferman has research, teaching, and extension appointments.  His research entails evaluating and/or developing wastewater treatment systems, waste to resource technologies, decision support models, and practices to retain nutrients in soil to maximize beneficial plant uptake.  He teaches the Department’s first technical course on basic engineering analysis of biological systems and an advanced water resource recovery class, jointly with the Department of Environmental Engineering.  He also teaches interdisciplinary sustainability classes in the Honors College.  His extension program entails, in part, facilitating an online professional continuing education onsite wastewater class and team teaching in the Extension Water School program.

PhD, Environmental Engineering, University of Cincinnati
