Mark Benjamin joined the UW CEE faculty in 1977, after earning his B.S. in Chemical Engineering from Carnegie-Mellon University in 1972, his M.S. in Chemical Engineering from Stanford University in 1973, and his Ph.D. in Environmental Engineering from Stanford University in 1978. Dr. Benjamin is an expert in physical/ chemical treatment processes in general, with long-term research interests in the behavior of natural organic matter (NOM) and its removal from potable water sources, and in the development of adsorption-based processes for removal of metals, NOM, and other contaminants from solutions.

For the past 20 years, a major focus of Dr. Benjamin's work has been membrane treatment of drinking water, and in particular approaches for interfering with membrane fouling by NOM. In addition to the topics noted above, Dr. Benjamin has published research on conventional coagulation and filtration processes, diffusion dialysis, and mineral dissolution kinetics. His work has been recognized by a Fulbright fellowship and several awards for best publications in various journals, and four of his students have won awards for best doctoral thesis in environmental engineering.

In addition to his research activities, Dr. Benjamin has served on the Board of Directors of AEESP and written graduate-level textbooks on Water Chemistry (Waveland Press, 2015) and Physical-Chemical Treatment of Water (with co-author Professor Desmond Lawler of the University of Texas, Wiley, 2013). He has twice held five-year appointments to endowed Chairs, and was selected as the AEESP Distinguished Lecturer for 2009-10. He served as co-advisor for the UW chapter of Engineers Without Borders (EWB) since its inception in 2005 until 2016. Professor Benjamin retired from the CEE Department in 2016 and is current President and CEO of MicroHAOPs, Inc., a small startup company developing improved pretreatment processes for membranes.
