Brief Biography

I am a graduate student in Decision, Risk & Operations division of Columbia Business School working with Prof. Assaf Zeevi, Prof. Vineet Goyal and Prof. Shipra Agrawal in Revenue management areas. My current focus is on dynamic learning in assortment optimization. I'm also generally interested in data driven modeling and estimation.

Prior to joining Columbia, I was a dual degree student in Electrical Engineering department at Indian Institute of Technology Bombay (IIT-B), where I spent an year in the Computer Science & Engineering department working with Prof. Sunita Sarawagi on my thesis in the area of probabilistic graphical models. I graduated from IIT-B in 2013 with Bachelor's in Electrical Engineering and Master's in Communication & Signal Processing.
