Welcome

I am a PhD student in the Explainable Machine Learning group, part of the Computer Vision and Machine Learning Department (D2) at the Max Planck Institute for Informatics on the Saarland Informatics Campus. I am supervised by Dr. Jonas Fischer and Prof. Bernt Schiele.

I work on foundation models for vision, where I developed the initial concept for CFM. I am currently working on grounding the chain-of-thoughts in large vision language models.
