Research Interests

  • Language Intelligence and Knowledge Engineering (LIKE)
  • Language Processing and Human-Machine Communication


  • Compilers: Principles, Techniques, and Tools.
  • Natural Language Processing.


I received my B.S. degree in Computer Science at Nanjing University in 1999, and my PhD in Computer Science at Nanjing University in 2005. I joined the Nanjing University as an assistant professor in 2005 , worked as an associate professor from 2008, and obtained professor in 2017. I have been on leave from Nanjing University from August 2010 to September 2011 to visit EECS Department and Statistics Department at UC Berkeley.
