Our research group investigates the prime role of atmospheric aerosol in shaping Earth’s climate and degrading air quality. An essential part of our mission is to develop innovative modelling tools to substantially advance the representation of the chemistry and physics involved in the aerosol formation and evolution in the atmosphere. In our studies we are utilizing these state-of-the-art modeling tools to provide an accurate assessment of the relationships between atmospheric aerosol, human-induced environmental changes, and future emission perturbations toward a sustainable environmental state.
