 My research is centred on computational models of argumentation. In particular, I am interested in the concept of persuasive argument within practical reasoning, reasoning about action. I am interested in modelling the reasoning involved in situations where decisions about actions need to be made, how this is done through the exchange of persuasive arguments, often in the presence of uncertain information, and how this reasoning can be represented for use in intelligent, autonomous software agents. I have demonstrated the applicability of my work in a number of different domains including law, medicine and politics. Within one such application aimed at supporting political debates about actions, I have developed an online discussion forum named Parmenides which makes use of a specific theory of argumentation in order to aid the gathering and analysis of the arguments involved in the debates represented. The (old) prototypical version of Parmenides can be accessed here, though the system is currently undergoing further developments to improve and extend it, with the latest version appearing here (- this new version has been implemented, and is maintained, by Dan Cartwright). Further details of my research can be found in my publications list.

I am also involved in a Knowledge Transfer Partnership (KTP) project, the Deeside Insurance Web Based Application Project, as academic support within the project team.
