I am a fourth-year PhD student in the Decision, Risk and Operations Division at Columbia Business School where I am fortunate to be advised by Prof. Hongseok Namkoong and Prof. Jing Dong. My research lies at the intersection of AI and Operations, with a focus on developing methodologies for large-scale operational problems. In particular, I work on uncertainty quantification and reinforcement learning, aiming to develop agents capable of efficient exploration and adaptive decision-making. Prior to joining Columbia, I was a Research Associate at Tata Institute of Fundamental Research Mumbai, where I had the privilege of being advised by Prof. Sandeep Juneja.
Before pursuing research, I worked at Ministry of Skill Development and Entrepreneurship (Government of India) as an Assistant Director in the Indian Skill Development Services (selected through UPSC Engineering Services Examination), implementing programs under the Skill India Mission aimed at building vocational training ecosystems for students from economically disadvantaged backgrounds. Before that, I worked at Indian Oil Corporation Limited as an Operations and Maintenance Engineer, where I optimized pipeline scheduling to meet fuel demand across distribution stations in the Northeast India. I hold a B.Tech in Mechanical Engineering from Indian Institute of Technology, Delhi.
