Biography
Born in Tirupati, a culturally vibrant and sacred city in southeastern India, my journey in science began as a curious school student, nurtured through my academic pursuits. This curiosity gained momentum during my bachelor's degree and was further honed during my master's studies. The foundation for my research career was laid during my tenure at the ISRO. My fascination with the ocean, atmosphere, and climate sciences deepened as I transitioned to roles at the CSIR-NIO and later at the ESSO-INCOIS under the Ministry of Earth Sciences, India. These transformative years shaped my passion for understanding Earth's complex systems and fueled my desire for exploration and research.
Driven by dedication and a relentless pursuit of knowledge, I had the privilege of contributing to multiple projects across disciplines and countries. These experiences eventually led me to Uppsala, Sweden, where I pursued and successfully completed my PhD in Meteorology from the Department of Earth Sciences at Uppsala University, as part of the Air, Water, and Landscape Science program (LUVAL). I am affiliated with the Centre of Natural Hazards and Disaster Science (CNDS), where I collaborated on interdisciplinary research addressing extreme weather and climate-related hazards.
My doctoral research, "Quantifying and Reducing Uncertainties in Studying Atmospheric Rivers and Moisture Transport: From Data and Heuristics to Scaling and Impacts", advanced our understanding of large-scale moisture transport and extreme weather phenomena. My commitment to unravelling the complexities of Earth's climate remains unwavering. This pursuit is not just a career but a lifelong dedication to scientific discovery and innovation.
