About Us

Dr. Nick Ralston

Director, Sage Green NRG

Sage Green NRG provides advice at the intersection between energy, economics, and the environment. Current projects range from resolving pollutant emission problems, improving public health and nutrition, identifying biochemical mechanisms of toxicity, and evaluating technologies which might be applied sustainably remove threats from environmental pollutants.   


Members of Sage Green NRG recently advised the U.S. National Academy of Science and worked on assignment with the United Nation’s Food and Agriculture Organization and World Health Organization as expert consultants regarding the new understanding of the substantial benefits that accompany maternal consumption of seafood during pregnancy.


Prior U.S. EPA and NOAA funded research by this team improved understanding of biochemical mechanisms of toxicity associated with high exposures to mercury and other toxicants that prompted development and approval of the Health Benefit Value (HBV) criterion defining the safety and benefits of maternal consumption of seafoods and freshwater fish in relation to child health outcomes.
