Ivan is the author of journal articles (JAIR, Artificial Intelligence, JANCL), conference papers (IJCAI, KR, ECAI, JELIA, AiML), and papers in refereed workshops (NMR, Commonsense, NRAC, M4M). He is a guest editor of the Special Issue of the Journal of Web Semantics on Reasoning with Context in the Semantic Web. Ivan is also co-chair of the ARCOE workshop series, and was co-chair of the Commonsense and NMR for Ontologies sub-workshop of NMR'10. He is a PC member of IJCAI'11 and AAAI'11, and has served in the PC of ECAI'10 and other conferences and workshops.
Ivan's main research interest areas are logic-based knowledge representation and reasoning, with focus on non-monotonic reasoning, modal logics and description logics. He has been working on belief change and reasoning about actions. Among his main current research topics are preferential reasoning, infra-classical logics, Horn belief change, non-classical belief revision, and ontology repair.
