About

I am a PhD student at Heinrich-Heine-Universität Düsseldorf under the supervision of Prof. Dr. Paul Swoboda, working at the intersection of deep learning and natural language processing.

My main research interests include, but are not limited to:

Improving LLMs without retraining

e.g. prompt engineering and efficient inference-time methods

🎯
Reinforcement learning for LLMs

training models to follow instructions and improve reasoning via RL

🧹
Machine unlearning

selectively removing knowledge from a model after training
