About Me

I am a postdoctoral researcher at the Department of Computer Science of Aalborg University. I work in the Data Engineering, Science and Systems (DESS) group in collaboration with Dr. Arijit Khan. I completed my Ph.D. in Informatics at the Eötvös Loránd University previously.

My research interests include data integration, ontology learning, knowledge representaion, and knowledge graph. Currently, I am keen on the topic of knowledge empowered machine learning, knowledge augmented model, and their applications in data management.
