Sarah Hörst is an Associate Professor in the Department of Earth and Planetary Sciences at Johns Hopkins University where she specializes in atmospheric chemistry. Her research focuses on understanding the formation and composition of planetary atmospheric hazes, especially the complex organic chemistry occurring in the atmosphere of Titan.Hörst received a B.S. in Planetary Science and B.S. in Literature from the California Institute of Technology in 2004. She started her research career studying Europa and Titan while at Caltech, then worked at NASA’s Jet Propulsion Laboratory after graduation, analyzing images of Saturn from the Imaging Science Subsystem (ISS) on the Cassini spacecraft. She went on to graduate school at the University of Arizona, where she studied the chemistry occurring in Titan’s atmosphere at the University of Arizona’s Lunar and Planetary Laboratory. After finishing her PhD in 2011, she was an NSF Astronomy and Astrophysics Postdoctoral Fellow at the Cooperative Institute for Research in Environmental Sciences (CIRES) at University of Colorado-Boulder.She is part of the Science & Engineering team for the Dragonfly mission to Titan.
