Research Assistant
Biography
I joined the ISG group in April 2011. My research interests lie in logic in computer science, coalgebraic semantics and knowledge representation. I obtained my PhD in 2006 at the University of Amsterdam (thesis title: Finitary coalgebraic logics). My supervisors were Alexander Kurz, Jan Rutten and Yde Venema. Since my PhD I have been working as researcher, first at the CWI Amsterdam, then at Imperial College London. Both in Amsterdam and London I have been lecturing (parts of) several courses on modal logic and automata theory. Furthermore I co-supervised the PhD thesis of Helle Hvid Hansen and a Master's thesis. I am one of the initiators of the Logic Seminar at Imperial and of an international workshop series that is concerned with the connections between Algebra, Coalgebra and Proof Theory.
In Oxford I am working within the ExODA project where I am studying query answering over databases relative to a given set of ontological constraints. These constraints are typically specified in Datalog± or some description logic formalism. The results obtained so far concern the application of so-called acyclicity conditions for query answering relative to DL-constraints and the extension of Datalog± with nonmonotonic negation in order to obtain a richer, more expressive contstraint language.

Boris Motik awarded EPSRC Early Career Fellowship
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].
