I like to say the monsoon has been my lifelong research collaborator—sometimes generous, sometimes unpredictable, but always fascinating. My academic journey began with a B.Sc. in Mathematics from Jadavpur University, followed by an M.Sc. from IIT Kanpur, and a Ph.D. in Atmospheric and Oceanic Sciences at the Indian Institute of Science, Bangalore. My doctoral work explored the space-time evolution of monsoon intraseasonal variability and its connection with extreme rainfall.
Afterward, I moved across the oceans—first as a Postdoctoral Research Scholar and Visiting Scientist at Florida State University, and later as a Scientist at IITM Pune and NCMRWF Noida—before returning to India’s east coast. Along the way, I have developed research interests in monsoon dynamics, extended-range prediction, and extreme rainfall, with a focus on intraseasonal oscillations and moist static energy budgets.
I have been fortunate to receive recognitions such as the INSA Medal for Young Scientists (2022) and the Roddam Family Medal (2019) for the best Ph.D. thesis at IISc. At IIT Bhubaneswar, I continue to explore new ideas with students and collaborators, while trying to make climate science both rigorous and fun. I try to understand the variability in different timescales, intraseasonal to multidecadal, while combining theories, observational studies and numerical simulations.
