Dr. Theodora Nah received her Hon. B.Sc. in Chemistry and Mathematics from the University of Toronto, and her Ph.D. in Chemistry from the University of California, Berkeley. Prior to joining CityU, she was a postdoctoral fellow at Georgia Institute of Technology. Dr. Nah's research interests are in environmental chemistry, with a focus on understanding chemistry important to atmospheric particulate matter (aerosols) and organic pollutants in aquatic ecosystems. Research in the Nah group utilizes a combination of fundamental laboratory studies, field measurements and theoretical modeling to provide a quantitative and molecular-level understanding of how air and water pollutants are produced, transformed within and removed from marine and coastal environments.
