01 About

I am a Member of Technical Staff at Black Forest Labs conducting frontier VLM research. Before that, I was an AI Researcher at Aleph Alpha Research, where I worked on byte-level foundational models.

I did my PhD at the University of Stuttgart, Germany, under the supervision of Andreas Bulling, where I focused on multi-modal models at the intersection of computer vision and natural language processing. Specifically, I developed novel VLMs geared towards conversational tasks such as visual and video dialog.

I hold a BSc and an MSc in the elite study program Simulation Technology at the University of Stuttgart. The latter was awarded with distinction and received the outstanding work award from the Industrial Consortium SimTech (IC SimTech).
