My research interests are:

- DB+AI (Integration of database and artificial intelligence technologies)
- Knowledge graph construction, refinement, and applications
- Natural language processing and machine learning/deep learning
- Similarity query processing
- High-dimensional data modelling, indexing, and query processing

I have obtained over 4.4 million funding in Australia and China. I have been awarded 6 ARC Discovery Projects. I have successfully lead two large-scale industrial projects focusing on various aspects of Knowledge Graphs, using a combination of machine/deep learning, NLP, data mining, and visualization techniques.

My research has generated significant impact. As of April 2018, my google citations is over 6,400, and my H-index is 40.
