About me
I am a third-year Ph.D. student in Computer Science at the Technical University of Munich (TUM) and CISPA Helmholtz Center for Information Security, supervised by Prof. Michael Backes. I work daily with Franziska Boenisch and Adam Dziedzic at SprintML Lab.
My research focuses on trustworthy and efficient machine learning: understanding what foundation models reveal about private data, verifying the provenance and ownership of deployed models, and making model adaptation more efficient.
I received my M.Sc. in Robotics, Cognition, Intelligence from TUM in 2023, graduating with high distinction, and my B.Eng. in Vehicle Engineering from Tongji University in 2020.
Research interests
- Privacy auditing and protection. Measuring privacy leakage in foundation-model embeddings and LLM adaptations, and developing privacy-preserving prompt transfer methods.
- Model provenance and ownership. Auditing the identity of agentic LLM APIs and fingerprinting generative models.
- Efficient machine learning. Architecture-agnostic structured pruning and efficient adaptation of foundation models.
See my publications for papers and project pages, or my CV for education and experience.
