About

Adam Belay Jamieson Career Development Associate Professor Computer Science & Artificial Intelligence Laboratory Department of Electrical Engineering and Computer Science MIT emailabelay (at) mit (dot) edu location_onStata Center, G996

I am an associate professor at MIT CSAIL. Before joining MIT, I completed my Ph.D. at Stanford University and spent a year at Google working on datacenter networking. My current research focuses on cloud computing and systems for machine learning. I am interested in building systems that make datacenters faster, more efficient, and more secure.

My research has won several awards, including research awards from Google and Meta, and the Sloan Research Fellowship.
