Portrait of Sai Srivatsa Ravindranath

I am a Research Scientist at Spotify, where I work on foundation models for personalization and recommender systems, as well as on multi-objective optimization.

I completed my PhD in Computer Science at Harvard University, advised by David Parkes. My research explored the intersection of deep learning, mechanism design, and multi-agent systems. During my PhD, I spent two years at Google Research working on projects at the intersections of mechanism design and LLMs, and auctions and reinforcement learning.

Before Harvard, I was a Research Fellow at Microsoft Research India. I received my B.Tech in Electrical Engineering with a minor in Computer Science from IIT Kharagpur.

Outside of research, I’m an active member of the MIT Outing Club and love hiking and skiing in the White Mountains of New Hampshire. I also love salsa dancing.
