In my research I started with core description logics. I created a SPARQL-DL evaluation engine inside the Pellet reasoner, and designed and initially implemented JOPA library for accessing OWL ontologies from Java. In my applied research activities I created (or led the development of) several ontologies in domains like relational datamining workflows, cultural heritage, aviation safety, and urban planning.
