My main research and teaching interests are in the areas of, Logic, Argumentation and Dialogue, and the Philosophy and Ethics of Artificial Intelligence
Current work involves research on non-monotonic logics, argumentation theory and dialectical models of reasoning that enable distributed reasoning amongst multiple agents (i.e., argumentation based dialogue).
I have worked on the ASPIC+ model of logic-based argumentation, dialectical models of logic-based reasoning that are provably rational under resource bounds, and models of logic-based argumentation that accommodate reasoning about preferences and values. The latter work was awarded
Winner of the AIJ 2014 Prominent Paper Award.
Recent research has focussed on the ethics of AI, and development of the above models of dialectical reasoning so as to integrate human and artificial agent reasoning through dialogue. The long term aim is to ensure that the AI machines of the future make decisions that are aligned with human values and preferences.
Other research interests lie in the areas of default reasoning, belief revision, non-monotonic logics, modal logics, and their applications in AI, Medicine and Law
