Shepherd is considered one of the leading climate scientists in America. A professor in the Department of Geography at the University of Georgia, Shepherd is director of the University’s Atmospheric Sciences Program. In addition to leading the AMS, the largest and oldest professional/science society in the atmospheric and related sciences, he serves on the National Oceanic and Atmospheric Administration Science Advisory Board, the Earth Science Subcommittee of the NASA Advisory Council, and the NASA Goddard Space Flight Center Visiting Expert Committee.
He is frequently sought as an expert on weather, climate, and remote sensing. In February 2013, he briefed the U.S. Senate on climate and extreme weather. Prior to joining the UGA faculty, Shepherd spent 12 years as a research meteorologist in the Earth-Sun Division at NASA-Goddard Space Flight Center. He was also deputy project scientist for the Global Precipitation Measurement mission, which launches this year. At UGA, he conducts research and teaching in atmospheric sciences, climatology, water cycle processes and urban climate systems. For his pioneering work using satellite data to investigate urban hydroclimate processes, in 2004 he received the Presidential Early Career Award for scientific research.
