Dr Chandan Sarangi is an Associate Professor in the Department of Civil Engineering at the Indian Institute of Technology Madras (IIT Madras) and the Principal Investigator of the CRRP2026-06MY-Sarangi project. His research advances understanding of atmospheric aerosols and their complex interactions with clouds, climate, precipitation and the cryosphere. Combining field observations, satellite remote sensing and advanced climate modelling, he investigates how aerosols influence regional climate, extreme weather, urban air quality, and snow and glacier melt across high-mountain environments. His research experience includes appointments at Pacific Northwest National Laboratory and collaborations with leading international research institutions, contributing to interdisciplinary efforts to address critical challenges in atmospheric and climate science.
