Short Bio

I am a postdoctoral researcher at Saarland University, advised by Prof. Alexander Koller. I work on NLP and ML, with a current focus on LLM reasoning. I am broadly interested in how current language models learn to reason, where they fall short, and how we can improve them. Please feel free to reach out to me for potential collaborations or just to say hi!

I recently finished my PhD studies at Utrecht University, where I was 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.
