Pinyan Lu (陆品燕)
Pinyan Lu is a Lead Researcher at Theory Group of Microsoft Research Asia. He is also a Chair Professor at Computer Science Department and Zhiyuan College of Shanghai Jiao Tong University. He studied in Tsinghua University (BS (2005) and PhD (2009) both in Computer Science). He is interested in theoretical computer science, including complexity theory, algorithms design and algorithmic game theory. Currently, his research is mainly focused on complexity and approximability of counting problems, and algorithmic mechanism design.
I'm looking for self-motivated students with interest in theoretical computer science working with me either as intern student at Microsoft Research Asia or as PhD student at Shanghai Jiao Tong University. For PhD students, I will supervise him/her with the help from the whole Chair Professor Team. If you are interested, please send me your CV.
There are also researcher (faculty) positions openning for theoretical computer science in both Institutes (MSRA and SJTU), please contact me if you are interested.
