I joined the NICTA lab and CECS at ANU in Canberra in August of 2011. I am working at the intersection of Artificial Intelligence and Operations Research on solutions to fleet logistics problems. I was a research fellow with the Intelligent Robotics Lab at the University of Birmingham 2008-2011; There I worked on a project investigating cognitive robots that could self-understand and self-extend.I was a researcher with the NICTA lab in Brisbane 2006-2008; There, I worked on fundamental research in AI Search, and simulation studies of city wide evacuation planning. I am the primary author of NRMDPP, runner up in the probabilistic track of the 2004 International Planning Competition. Co-author of ayPlanAgain, runner up in the multi-core track of the 2011 International Planning Competition. Co-author of best paper at the 2010 Pacific Rim International Conference on Artificial Intelligence. Co-author of gNovelty+, winner of the "Random" category at the 2007 International SAT competition. I have held an adjunct position with Griffith University since 2006. I have supervised a number of undergraduate students and visiting PhD students. Those include Dr Muhammad Shah (2011), Mayank Jain (2008), Acku Chauhan (2008), and Dr Aditi Barthwal (2003/04). I supervised a number of graduated PhD students, including Griffith University IIIS students Silvia Richter, and Nathan Robinson -- Dr Richter was awarded the 2012 John Makepeace Bennet Award for the best Australasian Doctoral Dissertation.
I am a computer scientist who works in a sub-field of Artificial Intelligence called Automated Planning. Although my interests extend to other subjects in Machine Learning and Automated Reasoning, my expertise lies mostly within planning. My goal is to study and develop planning technology that will allow machines (i.e., robots and computers) to reason about deliberations in their world, and to reason about how to extend their own model of the world intelligently. Specialties: decision-theoretic planning, non-Markovian rewards, probabilistic planning, relational reinforcement learning, SAT-based deterministic/classical and probabilistic planning.
