I've been pursuing a Ph.D in Computer Science at the University of Illinois at Urbana-Champaign since 2007. I work with Professor Michael T. Heath and Professor Jiming Peng.

Research

My research is concerned with numerical linear algebra and discrete optimization. In particular, I work on quadratic programming problems, with applications in data mining, machine learning and social networks.

Teaching

I've been a teaching assistant for several courses at Illinois since 2007.

• CS 105: Introduction to Computing with Application to Business and Commerce
  
• CS 357: Numerical Methods I
  
• CS 450: Introduction to Numerical Analysis
  

I've been an instructor at Nanjing University of Posts and Telecommunications from 2006 to 2007 and opened courses like Computer Multi-application, Programming Languages, and Data Structures.
