Dr. Sarath K. Guttikunda

Affiliate Associate Research Professor

Professional Interests

A TED fellow and a trained Chemical Engineer, Sarath's research interests follow from his thesis work on the “Impact of Asian Megacity Emissions at a local, regional and global level” from the Center for Global and Regional Environmental Research at the University of Iowa. He is now working as an independent researcher at UrbanEmissions.Info in New Delhi, India, and the developer of the SIM-air (Simple Interactive Models for Better Air Quality) family of tools, dedicated for sharing information on air pollution and climate change among the developing country cities with applications in cities like Delhi, Pune, Chennai, Dhaka, Manila, Hanoi, Shanghai, Lagos, and Tana. He was part of the team which built India's first air quality forecasting system, piloted during the 2010 Commonwealth Games in Delhi and now exploring opportunities to expand to other cities in Asia. For more information on his research www.urbanemissions.info.
