Mr Hector Manuel Perez-Urbina
Interests
My main research interests are in the areas of Knowledge Representation, Description Logics, and their application to to the problem of Information Integration.
I am currently working in the development of query rewriting algorithms for conjunctive queries over tractable Description Logics. We plan to implement such techniques in a real Information Integration framework in the near future.
Biography
I started my PhD at the University of Manchester in January 2005, under the supervision of professors Ian Horrocks and Ulrike Sattler. I was transferred to Oxford in October 2007; I am now a member of the Knowledge Representation and Reasoning group, working under the supervision of professor Ian Horrocks. In the summers of 2004 and 2005, I spent few months at the ENSIMAG in France, at the Laboratoire Logiciels, Systemes, Reseaux working on ontology-based data access under the supervision of Dr. Genoveva Vargas-Solar and professor Christine Collet. I received my Bachelor's degree (summa cum laude) in Computer Systems Engineering from the Universidad de las Americas, Puebla in Mexico in December 2004..
