Professional Interests
Applying interdisciplinary approaches to understand how thermal and photochemical reactions on surfaces affect the fate of pollutants in the environment and impact global climate

Current Projects
To visit the Raff lab website please go here: http://www.indiana.edu/~rafflab/.

The Raff group studies thermal and photochemical reactions that occur on environmental surfaces (e.g., airborne particles, buildings, vegetation, etc.). The goal is to understand the chemical mechanisms responsible for the degradation of surface-adsorbed chemicals (of anthropogenic and biogenic origins) and the formation of the chemical oxidants that lead to their transformation. We are particularly interested in obtaining molecular-level insights into these processes and to understand their effects on air pollution and climate. Research projects rely on an interdisciplinary and collaborative approach that provides group members with a strong background in analytical chemistry (e.g., spectroscopy, chromatography, and mass spectrometry), synthetic chemistry (e.g., the preparation of analytical standards and gaseous reactants), and heterogeneous chemistry (mechanistic studies of reactions occurring at the air-solid and air-liquid interface). In addition, we are interested in testing our theories and validating chemical mechanisms in the field.
