Sujoy Roy
Dr. Sujoy Roy is a Director of Tetra Tech Inc., located in Lafayette, CA. He holds a B. Tech. in Civil Engineering from Indian Institute of Technology, New Delhi, India (1990), and an M.S. and Ph.D. in Civil and Environmental Engineering from Carnegie Mellon University (1992, 1995). Dr. Roy is an environmental engineer with extensive experience studying water quality in aquatic systems in applied research and regulatory contexts, and has been involved in studies at the local, regional and national levels and participated in or directed studies with significant modeling, monitoring, and pilot testing components. Particular areas of interest include the modeling and development of management plans to address water quantity and quality concerns for drinking water source protection and for addressing ecological impacts. In most instances, this work is motivated by current impairment, or anticipation of future growth and climate change. Recent studies include the development of a selenium fate and transport model in San Francisco Bay, modeling and development of restoration plans for the restoration of the Salton Sea, and national assessments of water withdrawal sustainability in view of growing demands for electric cooling needs. Dr. Roy has provided support to the U.S. Environmental Protection Agency in the development of nutrient standards in surface waters in the states of California, Nevada, Arizona, and Hawaii. He also leads a multidisciplinary team of climate researchers evaluating climate change impacts to municipal water supplies from the Owens Valley watershed to Los Angeles. Various projects he has completed in the last five years include: modeling of contaminants of drinking water concern in California’s Central Valley and Sacramento-San Joaquin Delta, the development of a detailed master plan to manage land uses in the Mokelumne River watershed, and multiple studies evaluating the fate and transport of mercury in aquatic systems. Dr. Roy currently serves on a National Academy of Sciences panel on Missouri River Basin restoration.
