Biography

I am currently a lecturer in the School of Computer Science and Engineering (CSE) at The University of New South Wales (UNSW). I had worked as a lecturer in the Knowledge and Data Engineering research cluster within the School of Electronics, Electrical Engineering and Computer Science at Queen's University Belfast (QUB) from 2014 to 2016.

I did my PhD study in the School of Computer Science and Engineering (SCE), Nanyang Technological University (NTU) from August 2010 to October 2013, under the supervision of Dr. Gao Cong. Prior to joining NTU, I was a scientific assistant in the Center for Data-Intensive Systems (Daisy) in Aalborg University (AAU) from September 2008 to June 2010 under the supervision of Prof. Christian S. Jensen and Dr. Gao Cong. During October 2013 to September 2014, I was a research associate at the Data-Intensive Scalable Computing Lab, SCE, NTU.

I obtained my Master and Bachelor degrees from the School of Computer Science and Technology, Zhejiang University, Hang Zhou, China, in June 2008 and June 2006, respectively.


Research Interests

I am interested in Data Management (in particular, on geo-textual data), Databases, Information Retrieval, and Data Mining. My current research mainly focuses on spatial and textual data management, including:

I also have research experiences on:
