Current Research

My main research interest is to study the effects of anthropogenic and natural aerosols on earth's climate and air quality. The net effect on climate of greenhouse gases, aerosols, dust and clouds is a complex integral that is not well quantified. This is also due to gaps in our knowledge of real world particle optical, physical and chemical properties, and their spatial and temporal distributions. We study aerosol optical properties and their interaction with the solar radiation, with clouds and with snow by analyzing data and samples collected in different locations of the globe (from polluted urban areas to remote regions) on board aircraft or on the ground. We also study aerosol morphology and its relation to their optical properties. The goal is to provide new knowledge to advance the performances of future climate models and to improve air quality.
