    I am a graduate student in the Department of Atmospheric and Oceanic Science at the University of Maryland. My primary research interests lie in climate dynamics and in prediction and predictability.

    My doctoral research focuses on determining the potential predictability of summer monsoon rainfall and developing subseasonal-to-seasonal forecasts over the resource-stressed and densely populated South Asian region. Seasonal predictability is premised on the presence of influential climate system components with large thermal inertia. Upper ocean temperatures, in particular, meet that criterion but reliable long-term observational records are available mostly at the surface. The influence of sea surface temperature (SST) on South Asian monsoon is efficiently mined in our prediction effort.

    I am also interested in exploring El Niño-Southern Oscillation (ENSO) dynamics and variability, and characterizing such episodes using evolution-centric spatiotemporal SST analyses.

    Recently, I advanced to Ph.D. candidacy in May 2018. Meanwhile, I received my M.S. in Atmospheric and Oceanic Science from University of Maryland in 2016. My masters' scholarly paper is titled "The 2015-16 El Niño Episode: Classical Onset with Complex Evolution". Before joining the University of Maryland, I graduated with First Class Honors from Jadavpur University, Kolkata, India in June 2014 with a B.E. in Civil Engineering. In the summer of 2013, I was selected for the Indian Academy of Sciences' Summer Research Fellowship Programme (SRFP) in the Earth & Planetary Sciences category, and I had the pleasure of working with Dr. M. Rajeevan at the Ministry of Earth Sciences (MoES), Government of India. Also, I also did an undergraduate research internship in the summer of 2012 at the Indian Institute of Technology, Bombay with Prof. Subimal Ghosh and Prof. Subhankar Karmakar.
