I am currently a distinguished professor in the Department of Computer Science and Engineering at Shanghai Jiao Tong University (SJTU), as well as the co-founder and chief scientist of AISpeech. I am now leading the Institute of Intelligent Human-Computer Interaction of the Department of Computer Science, as well as the Center for Intelligent Speech and Natural Language Processing of the AI Institute of SJTU.

My academic journey began at the Department of Automation at Tsinghua University, where I completed my bachelor and master degrees in 1999 and 2002 respectively. I obtained my PhD at the Machine Intelligence Lab of the Engineering Department, Cambridge University, U.K. in 2006 and then worked as a senior research associate there. I joined SJTU in 2012 and founded SpeechLab at SJTU. Later, SpeechLab is extended and renamed as Cross-media Language Intelligence (X-LANCE) Lab as it is now.

My research interests primarily lie in the field of conversational AI, including rich aspects of speech and language processing as well as multi-modal linguistic computing. The goal of my research is to build cognitive conversational agent which can operate in complex real-world environment, deal with uncertainty, deliver information in a humanized way and evolve via interacting with environment. I have published over 200 peer-reviewed journal and conference papers and won numerous paper awards. I used to serve as program chairs for Interspeech, ICMI and SigDial, as well as area chairs of speech processing or dialogue systems for Interspeech, ACL, EMNLP etc.

The outcome of my research have been both recognized in academia and successfully industrialized. I founded AISpeech to commercialize state-of-the-art speech and language processing technology. AISpeech has been selected into the “AI Key Players” list in the Equity Research Report of AI by Goldman Sachs in 2016 and one of the Cool Vendors for AI (East Asia) by Gartner in 2017. On behalf of AISpeech, I am also leading the National AI Open Innovation Platform on Language Computing, granted by Ministry of Science and Technology of China in 2022.


     We are looking for self-motivated Ph.D./master/undergraduate students and postdocs interested in speech and language processing. Please send your CV to me if you want to join us.
