Daniel R Chavas is an Associate Professor in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. His research interests are in extreme weather, climate, and risk, including under climate change. His specialties are in tropical cyclones and in severe thunderstorms and tornadoes. He combines observations, theory, and real-world and idealized modeling to understand how these phenomena work, why our climate system produces them, and how we can better predict their hazards and impacts to society.
