Dr. Maffia spent the first 20 years of his career working as a process engineer and manager in the petrochemicals, mostly with the large oil company Atlantic Richfield, Inc. A few key projects included the Alaskan Pipeline and alternative fuels. In 1992, he joined academia at Widener University coming on as chairman of the Department of Chemical Engineering.

He has broad research interests in environmental, energy and biotechnology areas. For example, a specific topic being researched at Manhattan College is the development of environmental and biomedical technologies based on collagen nanofibrils (USP 6,660,829, USP 8,329,091). While at Widener, Dr. Maffia founded the Collagen Research Group, which has involved more than 300 students, industrial and government researchers, and faculty colleagues. In 2010, he retired from Widener as an emeritus professor, and shortly after, joined his alma mater, Manhattan College as professor of chemical engineering.

Originally from New Mexico, Robert Sharp is the Donald J. O’Connor Endowed Faculty Fellow of Environmental Engineering at Manhattan College, where he teaches and directs an externally funded research laboratory specializing in advanced water and wastewater treatment, biological regrowth and corrosion, water, and wastewater disinfection, and energy and resource recovery.In Dr. Sharp’s laboratory at Manhattan College, both graduate and undergraduate research assistants carry out fundamental and applied research in the areas of biological nutrient removal, anaerobic digestion, bioenergy production, resource recovery from wastewater, microbial ecology, pathogen disinfection and regrowth, plasmid stability, and bioremediation. His research results are detailed in more than 36 peer-reviewed journal articles and book chapters and he has presented over 50 papers at national and international environmental conferences.

Dr. Carbonaro’s affiliation with Manhattan College began as an undergraduate and he completed both his bachelor’s and master’s degrees from the College. After completing his doctorate at Johns Hopkins University in 2004, he became an assistant professor at Manhattan. Currently, he is a research associate professor of environmental engineering at Manhattan College and a Partner in the consulting firm Mutch Associates, LLC.

His current research interests include environmental chemistry, contaminant fate and transport in natural waters, soils and sediments, metal speciation, and in situ groundwater remediation. At Manhattan College, he has managed several externally-funded research projects related to chromium redox transformations, water quality monitoring of urban pollutants, modeling of metals in lakes for toxicity assessments and partitioning of metals onto organic carbon.


Dr. Kirk Barrett has served as an assistant professor in Manhattan College’s Civil and Environmental Engineering Department since 2011.

Kevin Farley is a Professor of Civil and Environmental Engineering and the Director of the Institute in Water Pollution Control at Manhattan College. His teaching and research focuses on water quality modeling, sediment contamination, bioaccumulation of toxic chemicals, and metals. Current research projects include studies on the mobilization of metals from contaminated sediments, on the development of a chemical speciation-transport model for metals in lakes, on the oxidation of chromium during drinking water disinfection, and on contaminant fate and bioaccumulation modeling of PCBs, dioxin/furans, PAHs, pesticides and mercury in the Hudson River and New York Harbor.

Dr. Farley has also served as a technical adviser and consultant on issues related to water quality, water quality modeling, sediment contamination and bioaccumulation of toxic contaminants. This has included scientific review panels for the EPA Chesapeake Bay Program, the National Research Council Committee on Remediation of PCB-Contaminated Sediments, the EPA Science Advisory Board panel reviewing the agency’s risk assessment framework for metals, and the UNEP International Panel for Sustainable Resource Management Metals Workgroup. Dr. Farley is currently serving as a technical consultant on several sediment contamination studies in New York-New Jersey Harbor, and has recently been appointed to the Ecotoxicity Technical Advisory Panel (ETAP), which serves as the cooperative research arm for the international nonferrous metal industries.
