Welcome!

We are a multi-disciplinary experimental group with research interests in the areas of Analytical and Physical Chemistry of airborne particles and environmental interfaces, driven by the overarching goals of understanding their impact on the atmospheric chemistry, the air pollution and the Earth’s climate. Our research efforts include three inter-related areas: Development and applications of new analytical methods for chemical characterization of aerosols; Chemical imaging and molecular-level studies of field collected particles; Laboratory studies of multi-phase chemistry of particles and interfaces.
