Chenhao (Vito) Wu

Short Bio

I am a Ph.D. candidate at the Chinese University of Hong Kong, supervised by Prof. Guoliang Xing. My research interests span all aspects of Computer Systems with a current focus on computer networks and networked operating systems. I am dedicated to some of the technically challenging problems in the real world and enjoy building engineering-heavy systems to generate real impact for a wide range of applications.

Prior to my Ph.D. study, I received my bachelor degree in Computer Science and Engineering from the Chinese University of Hong Kong, Shenzhen. My past experience lies in GPU-SM architectural design (GA102/GH102 ISA), and 802.11/LTE/5G-based protocol design (PHY/MAC). I am especially fortunate to have sensed the beauty of computer system design with my mentors in NVIDIA and learned how to do solid system research from Prof. Jun Huang, Prof. Shenghao Yang, and Prof. Ximing Fu.
