David A. Vaccari, Ph.D., P.E., BCEE, F.ASCE
Professor, Environmental Engineering
Stevens Institute of Technology

David Vaccari is a professor of environmental engineering at Stevens Institute of Technology in Hoboken, NJ. He has a masters and doctorate in environmental science and a masters in chemical engineering, all from Rutgers University. Originally focused on wastewater treatment and water pollution, he also specializes in modeling global phosphorus resource flows and in nonlinear statistical modeling in general. The specialization in phosphorus grew from involvement in planning bioregenerative life support for long-term space missions for NASA, from research for a textbook in Environmental Biology published by John Wiley, and from work on phosphorus pollution in streams for the NJDEP TMDL Task Force. The work in data analysis started with modeling of the activated sludge wastewater treatment process, and extended to modeling of pathogens in surface water.

Dr. Vaccari is a licensed professional engineer, a Board-Certified Environmental Engineer, and is listed in the Who's Who in Environmental Engineering and Science. He is the 2022 President-Elect of the American Academy of Environmental Engineers and Scientists.
