Dr. Naga Rajesh A
Dr. A. Naga Rajesh joined the Department of Physics and Nanotechnology, SRM Institute of Science and Technology (formerly known as SRM University) in 2015 after completing his Ph.D from Jawaharlal Nehru Technological University Hyderabad in the year 2015. He pursued his Ph.D in the field of signal processing. Dr. Rajesh is a climate scientist specializing in climate model analysis, monsoon and extreme weather, and land-atmosphere interactions, with a strong focus on the Indian subcontinent. His research spans the evaluation and projection of key climate variables such as temperature, precipitation, and extreme weather events using CMIP5/CMIP6 global climate models, including advanced bias correction techniques with deep learning. He has contributed to understanding the variability of the Indian monsoon, the occurrence of compound extremes, and the impacts of atmospheric processes such as sea breezes and aerosol interactions. Dr. Rajesh’s work also explores the relationships between climate drivers and vegetation, hydrology, and natural hazards such as lightning. His publications appear in leading journals including International Journal of Climatology, Natural Hazards and Pure and Applied Geophysics. He serves as a reviewer in various international peer reviewed journals.
