This $304,282 federal Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program supports research at Colorado State University (CSU) on the multiphase chemistry of biogenic sulfur compounds in the Earth's atmosphere. The principal investigator, Dr. Megan Willis, and her students will use laboratory experiments and kinetic models to quantify the effects of solvent environment on the ozone reactivity of dimethyl sulfide, methanethiol, and their oxidation products. This will improve understanding of how biogenic sulfur compounds undergo atmospheric processing, which influences the formation and growth of natural aerosol particles. The project also aims to develop STEM education materials on multiphase chemistry for middle and high school students. This 5-year award runs from April 2025 through March 2030.
