The Grassian group is interested in fundamental laboratory studies that provide a better molecular understanding of the surface chemistry of complex environmental interfaces. Several ongoing projects include understanding the molecular level details of the heterogeneous chemistry of trace gases with particulate matter such as mineral dust and sea spray in the atmosphere, dissolution and mobilization of Fe-containing particles, optical properties of atmospheric aerosol and applications and implications of nanoscience and nanotechnology in environmental processes and human health. The Grassian group applies the techniques and methods of surface science, aerosol science, microscopy and spectroscopy to study these problems.
