Dr. R. Saravanan is Professor and Head of the Department of Atmospheric Sciences at Texas A&M University. He is a climate scientist with a background in physics and has been a lead researcher using computer models of the climate for more than thirty years. He built an open source simplified climate model from scratch and has worked with complex models that run on the world’s most powerful supercomputers. He received his Ph. D. in Atmospheric and Oceanic Sciences from Princeton University and his M. Sc. in Physics from the Indian Institute of Technology, Kanpur. He carried out postdoctoral research at the University of Cambridge and subsequently worked at the National of Atmospheric Research in Boulder, Colorado. He helped create the TED-Ed animated short, “Is the weather actually becoming more extreme?” He is the author of The Climate Demon: Past, Present, and Future of Climate Prediction, which received the 2023 Louis J. Battan Author's Award of the American Meteorological Society
