WELCOME TO THE GRASSIAN GROUP WEBSITE!
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 and sea spray in the atmosphere, dissolution and mobilization of Fe-containing particles, geochemical interfaces, and applications and implications of nanoscience and nanotechnology in environmental processes. As you peruse this website, if you have any questions about our research please contact any of the group members.
September 1 - The Grassian group is now Gold certified from the Green Labs Program!! This certification reflects positive sustainability practices the group has been implementing and the group continues to strive to utilize the best environmentally-friendly approaches in all aspects of research.
August 23 - Congratulations to Mike for being awarded the NSF Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship!! Mike proposed research on the environmental organic chemistry of indoor gases and surface films as well as EDI work under guidance of Allen Goldstein at Berkley.
