I am a Senior Research Associate with the School of Computer Science and Engineering (CSE).

My research interests are in the areas of classical AI: knowledge representation, nonmonotonic and commonsense reasoning, planning, cognitive robotics, general game playing and multi-agent systems.

My work in robotics is mostly on the cognitive robotics challenge of making a robot reason and behave intelligently. I am particularly interested in the integration of different types of reasoning systems. For example, how do we connect a logical reasoner for planning high-level robot actions with the robot's vision and object recognition system. Such a tight-integration can lead to more effective behaviour. For example, the planning system can bias the robot's vision system in order to improve the detection of objects that the robot is expecting to encounter in its environment.

Finally, I am also focused on the application of AI technologies for solving knowledge driven combinatorial problems. This includes traditional optimisation problems such as resource allocation and logistics. In particular, I am interested in the use of Answer Set Programming (ASP) as a tool for concisely representing and solving these problems.
