About me
I am a Ph.D. student in the Modeling and Simulation group of Prof. Dr. Verena Wolf and in the Foundations of Artificial Intelligence group of Prof. Dr. Jörg Hoffmann. Also, I am a member of the Graduate School of Computer Science. Since December 2023, I work at the German Research Center for Artificial Intelligence (DFKI). Especially, I am involved in the Centre for European Research in Trusted AI (CERTAIN) and the department of Neuro-mechanistic Modeling (NMM).
