Research Interests

     My research focuses on patterns and processes related to aerosols and low clouds/fog and their roles in the climate system using satellite remote sensing. During my PhD at Ruhr-University Bochum, Germany, I studied interactions between aerosols, liquid-water clouds and their meteorological environment using satellite data with various statistical models. As a PostDoc at KIT, I have been working to better understand the role of aerosols and clouds in the climate system, ranging from local air quality research to regional and global scale analyses of fog and low clouds and their responses to a changing environment.
