Biography

Hi, I’m Keyu, a second-year master student in Machine Learning at University of Tuebingen. Currently, I’m a research assistant in Max Planck Institute for Intelligent Systems, working closely with Dr. Shiwei Liu and Dr. Jonas Geiping on efficient LLMs. I earned my B.Eng. in Artificial Intelligence from Southeast University where I was fortunate to be advised by Prof. Guilin Qi, and had a wonderful time at SEU-131AIClub, contributing to its founding and flourishing.

My current research focuses on scalable and efficient foundation models. Below are questions I am particularly passionate about:

• Reasoning with Accessibility: Why do LLMs have reasoning capabilities? How to calibrate uncertainty over intermediate reasoning states? What limits inference efficiency, and how to do more with less I/O without sacrifacing reliability?
• Optimization at Scale: How to effectively and efficiently optimize deep models? How does learning in a low-dimensional weights’ subspace allow a pre-trained model to adapt to downstream tasks, and will this make the model lose trustworthiness behaviours?
• Benchmarking in Principles: Do current task performance really capture how models behave, not just how they score and rank?

During undergraduate research, I broadly investigated on neuro-symbolic knowledge representation and reasoning, especially, handling of incomplete or inconsistent knowledge bases, and description logics.

I am open to research collaborations as well as internship or visiting opportunities. (uhhh, a little busy these few months…maybe until 03.2026? But I’d like to have any chats if you are interested!) Please feel free to reach out to me via email at​ ​keyu.wang@student.uni-tuebingen.de.
