This website describes the ongoing research projects in the Grassian laboratory as well as some of the state-of-the-art techniques that we use in our research. In general, we are interested in fundamental molecular-based 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 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. The Grassian group applies the techniques and methods of surface science, aerosol science, microscopy and spectroscopy to study these problems. As you peruse this website, if you have any questions about our research please contact any of the group members.
