Katja Poppenhaeger is the leader of the research section on "Stellar Physics and Exoplanets" at AIP and a professor at the University of Potsdam. She investigates exoplanets and their atmospheres, particularly in the environment created by their host stars through irradiation and magnetic effects. Her group uses both observations in several wavelength regimes as well as numerical simulations to increase our understanding of exoplanets and their host stars. For an overview on the various scientific projects her section works on, please go directly to the section website.
