Software Engineer, Google, Inc.

I'm currently a Software Engineer (SWE) at Google in Mountain View.
I work on Google News with some of the cool technology they've developed.

When I first joined the company I was a Site Reliability Engineer (SRE), but switched roles.

Research Interests (not necessarily job/google related):

• High-speed network protocols, including high-performance IP and TCP.
• Operating system internals (especially Linux) and optimization.
• Security and anonymity, for freedom to use the tools we create.
• Art, graphics, and computer vision. See my media page.

My Erdos number is 5.

1. Andrew A. chien (My PhD. advisor, many papers).
2. Ken Yocum (Improving Grid Resource Allocation via Integrated Selection and Binding).
3. Geoffrey M. Voelker (To Infinity and Beyond: Time-Warped Network Emulation).
4. Ron Graham (Maximizing data locality in distributed systems).
5. Erdos (They were friends, several ways).

Previous employment:

• I used to be a Graduate Student Researcher (GSR, aka RA) with the Concurrent Systems Architecture Group in the Computer Science and Engineering Department at the University of California- San Diego.
• I was an intern and later a contractor with Shannon Lab at AT&T; here's the Intern Guide.
• Before that I worked for the RADIANT team in CCS-1: Advanced Computing at Los Alamos National Lab as a Technical Staff Member (TSM) and later as a Visiting Scientist.
• And long long ago I was at the Space Science and Engineering Center at The University of Wisconsin as a student hourly.
