Our research focuses on atmospheric mechanisms and multiphase chemistry: molecular-scale chemistry across phases in Earth’s atmosphere, with global-scale implications for climate and air quality.

We study atmospheric chemical mechanisms and multiphase chemistry across a range of environments, from the remote marine atmosphere to indoor and urban atmospheres. To do this, we use field observations, laboratory studies and kinetic models to provide process-level information.

We are located in the Department of Chemistry at Colorado State University.
