Civil and Environmental Engineering

RESEARCH

 Professor Cappa's research is focused on the study of physical, chemical and optical properties of atmospheric aerosols. We use state-of-the-art analytical techniques in the lab and the field to characterize how and why aerosol properties vary in both time and space.
