Dr. Ho received his Ph.D. degree in computer science from The University of Hong Kong. His research interests include parallel and distributed computing and operating systems. Apart from academic research, he has been actively involved in R&D of distributed software systems for ten years. He was a main designer of the WhizzBee web server, the first cluster-based web server with an embedded cooperative caching support. He was the one from Hong Kong who won the first Google Summer of Code program where he developed two congestion control mechanisms and an API for bulk data transfer in Internet2. He has also managed two consultancy projects studying the high performance computing requirements and porting the Windshear and Turbulence Warning System for the Hong Kong Observatory.

Dr. Ho enjoys teaching and received the best tutors award from CS in 2005. He is a member of the Systems Research Group, and has helped build and maintain the Gideon and the newer Gideon-II clusters. He is a Unix/Linux fan, on which he has designed and implemented a low-latency transport protocol, a parallel disk I/O subsystem, and a fast process migration support apart from using it as his desktop OS.
