Currently, I am a Research Assistant in the University of Oxford. I joined the
Information System Group led by
Prof. Georg Gottlob and
Prof. Ian Horrocks in 2011 working in the
ExODA project, where I investigate
technologies of query answering and optimisations for expressive ontology-based data access.
The results obtained so far concern the application of so-called acyclicity conditions for
ontology-based query answering with forward chaining. I am also involved in the support of the
HermiT OWL 2 reasoner, dealing with the user-reported issues and inquire.
I obtained my PhD degree in 2011 at Griffith University, Australia, under the supervision of A/Prof. Kewen Wang, Prof. Rodney Topor, and Prof. Grigoris Antoniou (external). In my doctoral research work, I developed mechanisms and tools to support modifications of ontologies based on description logics. In particular, I have been working on ontology revision, merging and module extraction.
My research interests are in knowledge representation and reasoning, ontology-based technologies, and semantic web.

Doctoral Student Despoina Magka's paper entitled 'Ontology-Based Classification of Molecules: a Logic Programming Approach' has received the best paper prize at the 2012 Semantic Web Applications and Tools for Life Sciences workshop [more information].
Boris Motik was recently successful in gaining an EPSRC Early Career Fellowship. The 5 year project, MaSI3: A Massively Scalable Intelligent Information Infrastructure, focuses on Ontology-based Data Management Systems (ODMSs). These are a new kind of data management system specifically designed to deal with complex data, by using natural language queries often across multiple relevant sources [more information].
Yavor Nenov's PhD thesis "Computability of Euclidean Spatial Logics" has been awarded the Best Thesis Prize of the School of Computer Science at the University of Manchester [more information].
Ian Horrocks has been elected to join Academia Europæa, an eminent organization for European scholars. Academia Europæa was founded in 1988 and has over 2000 members, including around 40 Nobel Laureates [more information].
The Jaume I University of Castellon (Spain) has awarded a "Premio extraordinario de doctorado" (roughly translated as a Extraordinary Doctoral Award) to Ernesto Jimenez-Ruiz who is now a postdoctoral researcher at Oxford's Department of Computer Science [more information].
