I am a Senior Research Scientist at Google DeepMind in the Gemini team. I work in the model quality team in the post-training phase for Gemini, with a focus on SFT, RLHF and evaluation of Gemini’s instruction following capabilities.
I completed my PhD in 2023 in Computer Science at UMass Amherst advised by Prof. Mohit Iyyer in the UMass NLP lab. My research at UMass was supported by the Google PhD Fellowship. Before UMass, I received my undergraduate degree at IIT Bombay. During my PhD and undergrad, I also did some fun internships at Google DeepMind (Summer 2019 - Spring 2022), Allen AI (Summer 2022), Toyota Technological Institute at Chicago (Summer 2017) and Mozilla (Summer 2016).
I maintain a list of my publications under the Research tab. I also blog every now and then compiling my personal experiences.
