Principal researcher at the Machine Learning Research Group, Data61, CSIRO. I am also an adjunct associate professor at the Australian National University, and an honourary research fellow at the University of Melbourne.

My PhD in Computer Science was completed at the Australian National University in 2005. I was a postdoc at the Max Planck Institute of Biological Cybernetics and the Fredrich Miescher Laboratory in Tübingen, Germany. From 2008 to 2011, I was a lecturer in the Department of Computer Science at ETH Zurich, and in 2012 and 2013 I worked in the Diagnostic Genomics Team at NICTA in Melbourne. Since 2014, I am doing research with the Machine Learning Group in Data61, CSIRO in Canberra. Prior to my PhD, I researched and built search engine and Bahasa Malaysia technologies at Mimos Berhad, Malaysia. I obtained my B.E. (Information Systems) and B.Sc.
