Cohen has served as press secretary for the President's National Oil Spill Commission during the BP blowout in the Gulf. He comes to RFF from the US Environmental Protection Agency, where his positions included press secretary for then administrator William K. Reilly and a communications advisor under then administrator Carol M. Browner. "Dave is a fantastic addition to our team," said Pete Nelson, RFF's communications director. "I'm very excited to be working with him to make RFF an even better, more timely resource for journalists." "It is an honor to be with Resources for the Future," Cohen said. "In my view, this is the gold standard of environmental think tanks, regularly informing policy on the strength of objective analysis and innovative ideas. I look forward to helping media seeking information from RFF experts."
