Dr. Valentina Aquila is a professor in the Department of Environmental Science, American University. Aquila’s research aims to understanding the climate impacts of atmospheric aerosol, in particular in the stratosphere using global climate models and satellite observations. She has published several papers on stratospheric aerosol from volcanic eruptions and geoengineering via stratospheric sulfate injection, and is one of the coordinators of the Stratospheric Sulfur and Its Role in Climate (SSiRC) model intercomparison. Aquila received her PhD in Meteorology from the Ludwig Maximilian University of Munich, Germany, and carried out her doctoral research at the German Aerospace Center (Deutsches Zentrum for Luft- und Raumfahrt, DLR) of Oberpfaffenhofen. She completed her postdoctoral work at NASA Goddard Space Flight and at Johns Hopkins University, and joined American University in August 2017.
