Usha K Hasyagar

Dr. Usha K. Hasyagar is a Research Scientist with more than 7 years of specialized experience in climate modeling, data analysis, and visualization. She has worked extensively with climate models, as well as ground-based and satellite datasets. Her expertise spans regional-scale weather, air-quality modeling, aerosol-climate interactions, and hydro-meteorological extremes.

Dr. Usha’s most recent role was as a Project Scientist-I at the Centre for Atmospheric and Oceanic Sciences, Indian Institute of Science, Bengaluru. During her tenure, she investigated the impact of stratospheric aerosol injection geo-engineering on monsoon rainfall and streamflow using NCAR’s global climate model (CESM).

Previously, she served as a Research Fellow at the Space Physics Laboratory, Vikram Sarabhai Space Centre, where she fine-tuned and validated a regional climate model (RegCM) with a variety of meteorological and aerosol datasets. Her work included performing statistical analyses and visualizations, leading to 7 publications and presentations at several international and national conferences. She also studied the role of aerosols in snowmelt and runoff extremes over the Himalayas, and investigated aerosol-boundary layer interactions contributing to the amplification of South Asian haze and air quality deterioration.

Dr. Usha holds a PhD in Atmospheric Science from Kerala University, obtained in May 2023. She also has an MSc in Physics from the National Institute of Technology Karnataka.
