I am a third-year Ph.D. candidate in the Department of Computer Science at UCLA (2021-Present), co-advised by Prof. Kai-Wei Chang and Prof. Aditya Grover.
In my research, I have worked on vision-language alignment, reasoning, and generation. In addition, I am interested in understanding the feedback data that is used to improve large language models as assistants. Further, I have also contributed to climate and weather modeling.
I will join Google DeepMind in Montreal as Student Researcher in Summer 2024. Outside UCLA, I actively collaborate with Google Research (manager: Idan Szpektor, mentor: Yonatan Bitton) and Prof. Ludwig Schimdt at UW. I spent my Summer of 2022 at Amazon AWS AI (manager: Sravan Bodapati, mentor: Karthik Gopalakrishnan) . Before UCLA, I completed my B.Tech at IIT Delhi 2020 (advisor: Sumeet Agarwal). I have also worked at Goldman Sachs as an Analyst for a year (2021).
