Areas of Interest & Expertise
- Climate Change Research
- Regional Climate Modeling
- Monsoon Variability
- Weather/Climate Extremes
I am a climate researcher interested in understanding the science of climate change and its impacts. My research focuses on climate variability and climate change, particularly in extreme weather/climate events.
At the University’s Centre for Climate Change and Sustainability, I am also involved in developing high-resolution regional climate change scenarios for India and studying the impact of climate change on India.
My research examines the future changes in seasonal/sub-seasonal characteristics of temperature, precipitation along with their extremes. Before joining here, I worked as a post-doctoral researcher at the Indian Institute of Tropical Meteorology, Pune; Seoul National University, South Korea; and as a climate specialist at Qatar Meteorology Department, Qatar.
I received PhD and MSc in Meteorology from the department of Meteorology and Oceanography, Andhra University, India.
I have published several peer-reviewed papers in the aspects of Climate change and variability, climate impacts, monsoon variability and extreme weather/climate events.
