Hi there! I am Fajar, currently working as an Assistant Professor at the Institute of Data, Process, and Knowledge Management of WU Wien and as a (part-time) Postdoctoral researcher at the Data Science research unit of TU Wien. My research interest is mainly in the Semantic Web, Knowledge (Graphs) Engineering, and their interaction with Machine Learning approaches. I am also interested in applying such hybrid systems in various application domains, including Cyber-Physical Systems (CPS) and materials engineering.

I only updated this website every now and then; therefore please also check my webpage at TU Wien, WU Wien, and our Semantic System group website (http://semantic-systems.org) to get the latest news!
