Joschka Braun

I am a Machine Learning MSc student at the University of Tübingen, working in the Health-NLP group Tübingen.

Interests: I am interested in the intersection of Deep Learning and Natural Language Processing to develop AI systems that are capable, trustworthy, and socially beneficial. As AI technologies advance, I want to contribute to addressing the societal risks and ensure equitable benefits by improving scientific understanding and effective governance approaches.

Bio: I graduated with distinction in Computer Science from the University of Tübingen in 2022, ranking in the top 5% of my class. During my studies, I worked as a machine learning engineer at RAWLAB, a startup specializing in engineering data processing, where I applied machine learning models to time-series analysis. I am currently writing my Master's thesis on representation engineering in Large Language Models, supervised by Seyed Ali Bahrainian and Carsten Eickhoff from the Health-NLP group at the University of Tübingen, and Dmitrii Krasheninnikov and David Krueger from the Krueger AI Safety Lab at the University of Cambridge.
