Grassian Research Group

The Grassian group is involved in several research areas including surface chemistry of environmental interfaces, heterogeneous atmospheric chemistry, climate impact of atmospheric aerosols, and environmental and health aspects of nanoscience and nanotechnology.


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.


  • November 10 Irem Ustunol received 1st place in the “Nano Pitch” contest at the Sustainable Nanotechnology Organnization meeting held in Alexandria, Virginia. She was able to explain her poster and research in 100 seconds to the Nano Pitch judges and they were very impressed with what they heard. Congratulations Irem!!
  • October 11 – Prof. Vicki Grassian is named Fellow of the American Physical Society for her research on the physics and chemistry of environmental interfaces!!
  • September 11 – Congratulations to Haibin for passing his senate exam and advancing to candidacy!!!
