Curriculum Vitae
George Perkins Marsh Institute

 Dr. Sam Ratick received his BA in Mathematics from SUNY at Buffalo, and his PhD. in Geography and Environmental Engineering from Johns Hopkins.  Dr. Ratick served as an Environmental Scientist with the U.S. Environmental Protection Agency where he worked on a forecasting system that assessed current and future effects of economic activity on the environment and the effects of proposed environmental policies on the environment and economy. He also served as the Legislative Assistant for Energy and Environment to New York Senator Daniel Patrick Moynihan. His academic research work has focused on the development and use of analytical methods and mathematical models to aid the decision process for environmental assessment and management. He has been the principal investigator on grants and contracts from the Environmental Protection Agency, the National Science Foundation, the National Oceanographic and Atmospheric Administration, the Department of Energy, and the Army Corps of Engineers.  His recent funded research has been on measuring and mapping vulnerability to climate change.
