Hello! I am a third year BS/MS student in Computer Science at Stanford University, working on deep generative models with applications in language modeling, controllable speech synthesis and more.

I am an undergraduate researcher in the Stanford NLP Group and Stanford AI Lab, working under Professor Chris Manning. My research has contributed to state-of-the-art retrieval augmented systems. I was a part of Stanford NLP’s Chirpy Cardinal team, in the Amazon Alexa Socialbot Grand Challenge 5, where we secured the first place and a $250K prize in the Science category. There, I was responsible for the Pre-Firing Project, which aimed to predict user responses to improve response time. I was a Member of Technical Staff at Contextual AI, where I worked on training retrieval augmented language models.

News: RAPTOR got accepted at ICLR 2024.


My team and I won the Best Project (Sponser’s Prize) in CS224N (out of 650+ students).

My team and I were finalists at MIT Bitcoin Expo 2022 - Breaking Through Hackathon for creating a decentralized database validation protocol: ValGun.

My team won the Best Hardware Hack at Stanford TreeHacks 2021, for developing a EEG headset that allowed users to control a wheelchair.

I was awarded India’s highest civilian honour for U-18 citizens by Prime Minister Modi in 2020, for finding a method to reunite children back with their families using India's biometric-based national ID system: Aadhaar.
