I am looking for PhD/master students to work with me on various data usability and machine learning projects
If you are a highly motivated and creative student and interested in doing database research, please contact me (see prospective students)


I obtained my PhD in computer science from National University of Singapore (NUS), and was the winner of the Best PhD Thesis AwardI hold an honorary fellow position at University of Melbourne and a senior lecturer position at RMIT.  I am also the program manager of RMIT master of data science program.

My research is supported by Google, Australasian Research Council and Data61. I am generally interested in big data management, data visualization and machine learning. In particular, I enjoy designing end-to-end visualized data exploration systems for urban data, multi-dimensional data, and applying machine learning algorithms to solve traditional database query optimization problems.

Research Interests
I am highly interested in how to make data usable to data consumers, and make the implementation of such usability module as efficient and generalized as possible. In particular, I have been playing actively in: 


Research Topics:

    - Data Visualization & Visualized Data Exploration

    - Trajectory Data Mangement   

    - Geo-located Data Integration and Cleaning

    - Spatio-Textual query processing


Methodology:
    (1) Keyword Search, (2) Machine Learning Algorithm, 
    (3) Exploratory Search Paradigm
, (4) Data Provenance Tracking.
