    I have defended my dissertation and will join Google in Fall 2007

I am a Ph.D. candidate in the Systems and Networking Group at University of California, San Diego. I am interested in building experimental systems to solve real-world networking problems. My thesis focuses on diagnosing the performance of enterprise 802.11 wireless networks. I am co-advised by Stefan Savage and Geoff Voelker.

Short bio

I was born and raised in southern Taiwan. I got my BS degree in computer science from National Taiwan University in 1998. After collegue, I served in the Taiwan army as a telephone switch technician for two years. Then I spent another year developing Linux kernel mobile-IPv6 protocol in Siemens in Taipei. In 2001, I became a graduate student in UCSD CSE department. After work, I enjoy playing basketball, hiking, and skiing/snowboarding. Nowadays playing golf at the greater San Diego area, in particular the gorgeous Torrey Pines golf course, has become my biggest hobby.
