Hi, I'm Aidan. This is my "professional" homepage.
I have been working at the Digital Enterprise Research Institute based in the National University of Ireland, Galway since April 2005. I am currently a postdoctoral researcher within the Unit for Reasoning and Querying.
My general research interest is in exploring whether or not the Semantic Web and Linked Data are good proposals for the Web.
My ultimate research goal is to one day write a good research paper.
