Im an Ontologist at Google. I focus on Information Discovery, Data Integration, Ontology Based Data Access, Efficient Query Answering for OBDA and Relational Databases in Ontology Reasoning. The topic of my Ph.D. dissertation was the optimisation of query answering over ontologies by query rewriting techniques over SQL engines. The result of that research is now being applied in the development of the -ontop- framework for OBDA and the EU project Optique (see Projects).
I am interested in the development of efficient reasoning algorithms for light and medium weight ontology languages, in particular, RDFS, OWL..
