Short Bio

I am a postdoctoral researcher at Saarland University, as a part of Saarland Informatics Campus (SIC), advised by Prof. Alexander Koller. I work on NLP and ML, with a current focus on understanding and steering LLM reasoning, particularly through interpretability (esp. attribution). I believe this is a key to building safe and reliable AI systems.

I recently finished my PhD at Utrecht University, advised by Dr. Dong Nguyen and Prof. Albert Gatt. Before that, I received my master’s (Computer Science, advised by Dr. Yuanbin Wu) and bachelor’s (Psychology) degrees both from East China Normal University.
