I gained a BSc degree in Electronic and Information Systems followed by an MSc degree in the same area at XiDian University (XiDian University ranks second in Electronic and Information Systems amongst universities in China). After 1997, I worked on data transmission over wireless local area network at the State Key Laboratory on Integrated Services Network (XiDian University) and National Technology Center (ShenZhen Electronics Group).

In 2005, I obtained a PhD. degree in computer science from the University of East Anglia (UEA). My thesis was on intelligent call routing using techniques of speech recognition and natural language processing. From 2006 to 2009, I worked as a Research Fellow at the Knowledge Media Institute of the Open University, Milton Keynes, and then moved briefly to the Robert Gordon University, Aberdeen, where my research was on information retrieval and data mining. I moved back to the University of East Anglia and worked as a senior research associate on adaptive cognition for automated video analysis. Since March 2013, I am working as a senior researcher on an interactive system using multimodal information in the School of Informatics at the University of Edinburgh. My research is focused on multimodal information processing (speech/audio signal processing, natural language processing, and vision computing). I have special expertise in three areas that are used in this project:

(1) multimodal information processing and information integration by signal processing and language modelling;

(2) knowledge acquisition and information inference using techniques of machine learning algorithms and semantic analysis;

(3) dynamic adaptation of acoustic and language models for speech recognition and audio event detection.
