The Grassian group focuses on the chemistry and impacts of environmental interfaces. These interfaces include atmospheric aerosols, aqueous microdroplets, engineered and geochemical nanoparticles, and indoor surfaces.

This website describes the different research areas 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 molecular-based laboratory studies that provide a better understanding of the chemistry of complex environmental interfaces. Several ongoing projects include understanding heterogeneous chemistry of trace gases, including organic and inorganic compounds, with particulate matter such as mineral dust and sea spray in the atmosphere; aqueous interfacial chemistry within microdroplets and water thin films; dissolution, mobilization and multiphase chemistry of Fe-containing particles and transition metal ions; sulfur oxidation chemistry in aqueous aerosols; multiphase chemistry/photochemistry of nitrogen oxides that lead to HONO formation in indoor and outdoor environments; geochemical nanoparticle surface chemistry and their interactions with biological molecules (eDNA and proteins); particulate matter and human health; applications and implications of nanoscience and nanotechnology in environmental processes and human health.  As you peruse this website, if you have any questions about our research please contact any of the group members.
