Dawn Emil Sebastian is a hydrologist specializing in assessing climate change impacts on the water sector and examining the critical role vegetation plays in the hydrological cycle. She recently earned her Ph.D. from the Indian Institute of Technology Bombay, focusing on the intricate Role of Vegetation in Land-Atmosphere Moisture Interactions. Her research delved into how vegetation’s response to hydro-meteorological variables varies across different spatio-temporal scales and integrated these insights into a comprehensive hydrological modeling framework.She has a Bachelor’s degree in Civil Engineering from University of Kerala and a M.Tech in Water Resources Engineering from Indian Institute of Technology Bombay.

 

Before joining IIHS, Dawn served as Scientist B at the Centre for Water Resources Development and Management in Calicut, Kerala. In this role, she contributed to many research and consultancy initiatives aimed at enhancing water resources management, especially addressing the rising climate related disasters. She also organised numerous training programs, educating Kerala’s stakeholder departments on climate change and its implications for water resources.
