I am an associate professor at Norwegian University of Science and Technology (NTNU). I was previously a postdoctoral research fellow at University of Oslo as a member of Logic and Intelligent Data research group. I was also a visiting researcher at University of Oxford and a postdoc at University of Leuven. I received my PhD degree in computer science in 2012 from University of Leuven. I received my M.Sc and B.Sc. degrees in computer engineering from Işık University in 2008 and 2006 respectively.

I took part in several EU projects (FP7, FP6, Erasmus etc.) such as iCamp, ROLE, LEGIS, LEFIS, and TREE. I am presently conducting research on visual query systems within the Optique project (FP7).

My main research interests fall into ontology-driven information systems and ontology-driven design of information systems from a human-computer interaction perspective. My current research, within Optique project, addresses visual query interfaces for ontology-based data access, where ontologies are exploited both for scalable end-user query formulation and for query answering for Big Data.

My research interests also include: pervasive computing, context-aware computing, adaptive computing systems, human-machine interaction, end-user development, metadata and semantics, ontological engineering, semantic web, formal modelling, knowledge representation, software engineering, database systems, model driven development.

I currently sit on the editorial boards of Journal of Web Semantics and International Journal of Privacy and Health Information Management.
