Riley Duren recently joined the University of Arizona’s Office of Research, Innovation and Impact as a Research Scientist. He also maintains a joint appointment as an Engineering Fellow at NASA’s Jet Propulsion Laboratory. His NASA experience to date has included roles on nine earth and space science missions (with the Shuttle Radar Topography Mission and Kepler being personal favorites). From 2008 to 2019 he served as Chief Systems Engineer for JPL’s Earth Science Directorate, supporting a wide range of satellite and airborne missions, research and applied science programs. His own research applies multi-scale earth observations and the emerging discipline of science systems engineering to inform societal responses to climate change. He is Principal Investigator of the California Methane Survey and Methane Source Finder projects and Program Executive for a new public-private partnership developing a constellation of small satellites to support climate and conservation action.
