In August 2011 I will have joined the Optimisation Group at NICTA, based at the Canberra Research Lab. From November 2008 until August 2011 I was with the Intelligent Robotics Lab at the University of Birmingham. I also hold an adjunct position with Griffith University IIIS. From May 2006 until November 2008 I was a Researcher with Abdul Sattar's "SAFE Agents Work Package" based at the NICTA Brisbane Research Lab. Before that I was a PhD candidate at the Computer Sciences Laboratory at the Australian National University.
Artificial intelligence:
Planning – switching, decision-theoretic planning, relational generalisation, non-Markovian rewards and dynamics, and control knowledge
Machine Learning – Relational reinforcement learning, policy gradient, explanation based (analytical) learning
Knowledge Representation and Reasoning -- reasoning about actions, semantic web (ontology) and description logic
Search – bistate pruning, stochastic local search, anytime algorithms

ay-Also-Plan – co-author with Juhan Ernits. Runner up at the Sequential Multi-Core track of the International Planning Competition, 2011. This was a very surprising result for us, as the system was designed for massively parallel compute clusters, not a 4 CPU/ 8 core machine. The winning entry at IPC-2011 was Arvand Herd by Hootan Nakhost et al.
c++-0x libraries I had written in 2008-09 for CogX. CAST_RPC makes writing procedural interactions between CAST (CoSy Architecture Schema Toolkit) components easy. And cassandra is a Parsing Expression Grammar based on Colin Hirsch's pegtl (Parsing Expression Grammar Template Library) for parsing POMDP problem files. The latter now includes Finite-State Controller evaluation and improvement functionality.

CO-PLAN (2008) -- co-author with Nathan Robinson and Duc-Nghia Pham. Combining SAT-Based Planning with Forward-Search
ayPlan (2008) -- Cost-optimal (also has a satisficing mode) state-based propositional planning (this is a module from CO-Plan)
Evacuator (2007) -- co-author with Duc-Nghia Pham. Simulates pedestrian evacuation from the Brisbane CBD (email me for details)

Some interesting music (7/1998, 9/1998)
My brother has released a CD of 20th century guitar music. Order it here.
