In my research I am interested in applying techniques from automated theorem proving, logic, and complexity theory to knowledge representation and reasoning, and in particular for reasoning in description logics and ontology languages. The topics of my works are quite diverse. I have been working with Hans de Nivelle on the development of resolution-based procedures for various fragments of first-order logic, with Boris Motik on resolution-based procedures for description logics, and with Bernardo Cuenca Grau, Ian Horrocks and Ulrike Sattler on the topic of modularity in ontolgies. Recently, I have been working with Birte Glimm on role conjunctions in expressive description logics, and with Ian Pratt-Hartmann on complexity of graded modal logics. The primary focus of my current work is consequence-based ontology reasoning procedures. I develop a prototype reasoner CB based on such a procedure.
Currently I am working as a Research Assistant at the Oxford University Computing Laboratory and researcher co-investigator for the EPSRC-funded project ConDOR. Previously I was a Research Associate at the University of Manchester funded by the EPSRC project REOL and a PhD student in the Max-Planck-Institut fuer Informatik, Saarbruecken, Germany. I obtained my PhD degree in computer science from the University of Saarland in Germany and my first degree in mathematics from the Moscow State University in Russia.
