(2002) and B.Sc. (2000) in Computer Science from the Federal University of Paraná, Brazil.
Ivan has co-authored more than 40 peer-reviewed publications ranging from articles in journals (JAIR, Artificial Intelligence, JANCL, Logica Universalis), full papers in international conference proceedings (IJCAI, KR, ECAI, AI, JELIA, AiML, TARK), and papers in international workshops (NMR, Commonsense, NRAC, M4M, DL). He has been a guest editor of the Special Issue of the Journal of Web Semantics on Reasoning with Context in the Semantic Web. Moreover, Ivan is one of the founding members and co-chair of the ARCOE workshop series. He is also a PC member of IJCAI’13, AI’13, RR’13 and NRAC’13, and has served in the PC of KR’12, IJCAI’11, AAAI’11, ECAI’10 and other international conferences and workshops.
Ivan’s main research interest area is logic-based knowledge representation and reasoning, with focus on modal and description logics and their applications in defeasible reasoning, reasoning about actions and change, and the semantic web. His main current research topics are non-monotonic reasoning in more expressive languages, non-classical belief change, and ontology repair and maintenance.
