Dr. Cohen leads water resources and environmental contamination projects that involve site investigation and remediation, brownfields redevelopment, risk-based corrective action, and modeling of contaminant fate and transport. Dr. Cohen has led water resources and geological investigations throughout the United States and in Turkey. For the United Nations Development Programme (UNDP), he completed the first-ever comprehensive environmental assessment of Cyprus’ largest copper mining and mineral processing complex.

Dr. Cohen serves as an expert witness for groundwater contamination cases that have addressed PFAS, MTBE, chlorinated solvents, and other contaminants. In addition to his research and case-study publications, Dr. Cohen is co-editor of the American Geological Institute’s Geoscience Handbook (AGI Datasheets, 4th Edition).
