Ravishankara

Ravishankara is a Professor in Chemistry and Atmospheric Science at Colorado State University, with over 40 years of research on atmospheric chemistry. Former Director of NOAA's Chemical Sciences Division, his work addresses ozone depletion, climate change, and air pollution chemistry.

Research spans:

• Laboratory measurements of fundamental atmospheric reaction kinetics
• Quantifying ozone-depleting substance impacts
• Developing climate-friendly chemical alternatives
• Regional air quality modeling in developing regions

Publications consistently advance understanding of radical-mediated oxidation processes and ozone layer dynamics. Recent work examines wildfire impacts on stratospheric chemistry and nitrous oxide mitigation strategies.

Honored with Polanyi Medal and EPA Ozone Protection Award. Serves on multiple international scientific assessment panels including UNEP Vienna Trust Fund chair.
