Xingbo Wu (吴兴博) I'm a Senior Researcher at Microsoft Research based in Cambridge UK since January 2022. My research interests lie in the area of performance and efficiency of computer systems. More recently, I focus on systems and networking infrastructure for next-gen AI datacenters. Before joining MSR, I was a tenure-track assistant professor at UIC CS. I received my Ph.D. from UTA CSE, advised by Dr. Song Jiang.
