## Current and Past Affiliations

• Mathematics of Networks and Systems Research Dept at Bell Laboratories, Alcatel-Lucent, 1997-Present.
• Massachusetts Institute of Technology.  PhD in Applied Mathematics, 1993-1997.

Thesis: An Analysis of Network Routing and Communication Latency. ps.gz

• Wellesley College. summa cum laude, BA in Mathematics and Computer Science, 1989-1993.

I was born and brought up in Shanghai, China. I spent eight years of my childhood in Jing'an District Primary School and Kindergarten, and six years of my adolescence in Yucai High School. I arrived in America in the summer of 1989 and spent the next eight years in the Boston area, first studying at Wellesley College then at MIT. In 1997, after my Ph.D, I landed a research position at Bell Labs in Murray Hill, NJ, and it remains the only job I have had. At the time Bell Labs was the research arm of Lucent Technologies. It was spun off from AT&T in 1996 and merged with Alcatel in 2006.

My research broadly concerns algorithmic and complexity issues of networking, which includes network planning and optimization, routing and scheduling protocols, and stability and Quality-of-Service analysis. My work is interdisciplinary, covering topics in theoretical computer science, applied mathematics, operations research and electrical engineering.

Right now I'm serving on the organizing committees of IEEE FOCS 2016 and the 5th Women in Theory Workshop 2016. In the past, I served on the committees of ACM STOC 2014, 2009, 2001, IEEE FOCS 2011, IEEE Infocom 2007-2015, ISAAC 2011, IEEE IPDPS 2010, ACM-SIAM SODA 2009, ACM SPAA 2009, ACM PODC 2008, APPROX 2007, DCOSS 2007. In 2013 I taught an Analysis of Algorithms course at Columbia University, which I really enjoyed.

More details of my work can be found in my curriculum vitae.
