Lead Senior Scientist
Dr. Rudek is a Lead Senior Scientist with Environmental Defense Fund, a position he has held since 1996. He holds a Ph.D. (1992) in environmental biology from the University of North Carolina at Chapel Hill. Dr. Rudek also holds an adjunct Associate Professorship in the Department Earth, Marine and Atmospheric Sciences at North Carolina State University.
He works across a variety of arenas within EDF’s areas of focus. He works to measure and reduce GHG and nitrogen emissions from agriculture, especially low carbon rice farming, and livestock manure management. He is also the technical lead for EDF’s work on methane emissions from natural gas end use sectors such as electric generation, industrial use, urban neighborhoods and heavy duty trucks. Dr. Rudek also provides technical guidance to EDF’s efforts on sustainable supply chains for major retailers.
Dr. Rudek lives and works in the Philadelphia area.
