Hi! I am Duan Keyu (段柯宇).
I am currently a Ph.D. student in the School of Computing at National University of Singapore. I am advised by Dr. Qizhe Xie. Before joining NUS, I spent two wonderful years learning with Dr. Xia (Ben) Hu at DATA LAB in Texas A&M University and Rice University. Before that, I obtained my B.E. of Software Engineering from Beihang Univeristy.
My research interests lie in LLM post-training, reasoning and building generalist agentic AI..
I am in the job market and actively seeking opportunities. If you are interested in collaborating or have any potential openings, please feel free to reach out !
