About me

I am a third year PhD student in Computer Science department at UC Santa Barbara where I have been fortunate enough to be advised by Prof. Yu-Xiang Wang. My research primarily focuses on developing parameter-free online learning algorithms that can optimally cope with non-stationarities present in the environment. Applications of my work include forecasting trends in Time Series, adaptive Total Variation denoising, non-stationary Multi Armed Bandits… (I am trying to expand this list :-). I received my Bachelors and Masters degrees in Electrical Engineering from Indian Institue of Technology, Chennai during 2016.
