Area of study
I obtained my PhD from the Australian National University(ANU) in 2003. My PhD work was on the caching for object oriented databases. Then in 2003 I did a postdoc at the university of Vermont, working on optimization issues relating to relational databases. In 2004 I began work as a lecturer in La Trobe University. In La Trobe university I have worked on many different research topics, include: Big Data, relational database optimization, wireless sensor networks, moving object databases, flash database, location based services.
