Short Bio
I am a postdoctoral researcher at Saarland University, advised by Prof. Alexander Koller. I work on LLM reasoning, and am broadly interested in how language models learn to reason, their limitations, and how these limitations can be addressed. Please feel free to reach out to me for potential collaborations or just to say hi!
I recently completed my PhD studies at Utrecht University, where I was primarily advised by Dr. Dong Nguyen. During my PhD, I also spent time at LMU Munich and Amazon. Before that, I studied computer science and cognitive science at East China Normal University, where I was advised by Dr. Yuanbin Wu.
