Senior research scientist at Siemens AG Österreich. External lecturer at FH Krems. I received my PhD in Computer Science from TU Wien, where I studied different methods to prepare Linked Data for data analysis under the supervision of Prof. Axel Polleres. My research interests include data management, knowledge representation, and semantic web technologies.
