About Me

I am a final-year undergraduate student of Computer Science at the University of Leipzig. My research looks at how internal representations of deep learning models can influence model reliability and performance. My thesis is being advised by Prof. Färber at Technische Universität Dresden.
This summer, I will join Prof. Lo's lab at National Taiwan University as a visiting researcher.
Previously, I conducted ML research at the Max Planck Institute for Mathematics in the Sciences under Dr. Taha, and interned at ScaDS.AI. I have also spend a semester at NTUST in Taiwan and completed an internship at TSMC. Furthermore, I worked as a student tutor at the University of Leipzig.

Research Interests

My research focuses on improving the reliability and trustworthiness of deep learning models, including LLMs, by finding patterns in and manipulating internal representations, for example through relative latent spaces or via watermarking of training samples.
