I am a third-year PhD student in Computer Science at Stanford University,
co-advised by Prof. Jure Leskovec
and Prof. Carlos Guestrin.
Before this,
I spent a lovely year learning under
Prof. Zachary Lipton
as a visiting researcher at Carnegie Mellon University (CMU).
I did my undergrad in CS at IIT Delhi,
where I was the President's Gold Medalist for the class of 2022.
I am a machine learning (ML) researcher.
My current focus is relational foundation models (RFMs):
large-scale pretrained models that can understand and reason about relational data
(including tables, time-series and graphs)
to solve complex decision-making, forecasting and recommendation challenges
(e.g., see this).
In my free time,
I like to swim, watch movies, and
read.
