Khaled Saab

I am currently a Research Scientist at Google Research. I received my PhD and MS in Electrical Engineering from Stanford in 2023 and 2019, and BS in Computer Engineering from Georgia Tech in 2017. At Stanford, I was lucky to be advised by Daniel Rubin and Chris Ré.

My current research focuses on multimodal foundation models for healthcare.
