Roxy Mathew Koll

Roxy Mathew Koll, IITMDr. Roxy Mathew Koll is a Climate Scientist at the Indian Institute of Tropical Meteorology, and an Adjunct Associate Professor at the University of Pune. Before joining IITM, he worked as a Research Scientist at the Euro-Mediterranean Centre on Climate Change, Italy. He did his PhD in Ocean and Atmospheric Dynamics from Hokkaido University, Japan.

Roxy is currently leading research on climate change and its impact on the rapid warming in Indian Ocean, the monsoon and the marine ecosystem. He is a Co-Chair of the CLIVAR Indian Ocean Region Panel, and a Lead Author of the IPCC Special Report on Oceans and Cryosphere in a Changing Climate. He was named the Kavli Fellow by the U.S. National Academy of Sciences in 2015. The Indian Meteorological Society felicitated him with the Young Scientist Award in 2016, for his research on the changes in the Monsoon.

Presently, Roxy is visiting PMEL/NOAA, Seattle as a NAS/NRC Senior Associate.
