Biography

Chuangtao Ma is a postdoctoral researcher at the Department of Computer Science of Aalborg University (AAU). He works in the Data Engineering, Science and Systems (DESS) group with Prof. Arijit Khan. He previously received his Ph.D. in informatics from Eötvös Loránd University (ELTE).

His research interests lies in explainable decision-making with knowledge-grounded LLMs and AI Agents. His work spans knowledge graphs, graph retrieval-augmented generation, LLMs and Agents for tworthworty AI and their applications in data and knowledge management.

I’m currently on the job market, seeking faculty or research scientist positions. Feel free to reach out if you consider me a good fit whether it’s a research collaboration, or a potential opportunity!
