Paul Shepson

Paul Shepson is the Dean and Distinguished Professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University. His research focuses on atmospheric chemistry and climate change, particularly Arctic halogen chemistry, greenhouse gas emissions, and aerosol dynamics. He leads projects like the CHACHA campaign studying Arctic atmospheric chemistry and the Airborne Laboratory for Atmospheric Research (ALAR).

• Education: Ph.D. in Chemistry from Pennsylvania State University (1982).
• Research Themes: Arctic ozone depletion, greenhouse gas quantification, and halogen activation mechanisms.
• Key Contributions: O-Buoy project for autonomous Arctic measurements, BROMEX field campaigns, and urban emission studies in NYC.

His work integrates airborne and ground-based observations with modeling to address climate impacts and pollution mitigation. Collaborations include NASA, NOAA, and international institutions.
