  Research Leadership

• As the project leader and principle researcher of the NICTA VALACON (Visualisation and Analysis of Large and Complex Networks) Project 2004-2007, I led a research team of 15 people (3 postdoctoral researchers, 2 research engineers and 10 PhD students).
• The VALACON project achieved research excellence, publishing 100+ research publications in high quality journals and conferences, 30 conference poster papers and Technical reports, 10 PhD Theses, and a visual analytic tool GEOMI (Geometry for Maximum Insight).
• The research excellence of VALACON project was acknowledged internationally; we won 5 awards and prizes at the international competitions.
