Expetise

I have been working on data mining research and applications from 2001, and am currently a Data Scientist with IBM Australia.

Prior to that, I was a Senior Data Scientist at Australian Government from 2009 to 2016 and an Australian Postdoctoral Fellow (Industry) with University of Technology, Sydney from 2007 to 2009.

My research interests include clustering, association rules, time series, outlier detection, social network analysis and data mining applications. I have over 60 papers published in journals and conference proceedings.

I am a senior member of the IEEE, and served as program committee member for more than 40 international conferences.
