Kai Wu   (Kyle)

I am a senior engineer at Microsoft. Previously (2021-2022), I was a researcher at ByteDance (TikTok) Infrastructure System Lab. Before that, I received my Ph.D. in Electrical Engineering and Computer Sciences from University of California Merced, working with Prof. Dong Li on building efficient and scalable system supports for heterogeneous memory-based platforms. My research interests mainly focus on high performance computing (HPC), computer systems, runtimes, and programming models.
