EPA Senior Research Scientist Dr. Richard Zepp's research interests include nanomaterial's (a class of small-scale  substances less than 100 nanometers in size) transformation in the environment, keeping recreational waters safe, and how climate change might affect ecosystems.Dr. Zepp is an Adjunct Professor at the Rosenstiel School of Marine and Atmospheric Sciences, University of Miami, Florida and at the State University of New York, Syracuse (Department of Chemistry). Since 1995, he has been a member of the United Nations Environment Programme Panel on Environmental Effects of Ozone Depletion.
