Sihan Yang

Hi there! I am a senior student at the University of Electronic Science and Technology of China. I will join The Chinese University of Hong Kong as a PhD student in Fall 2026. Previously, I have spent wonderful time at Shanghai AI Laboratory.

I'm interested in internship or collaboration opportunities on foundation model architectures, especially linear sequence modeling. If you have any such opportunities, please feel free to contact me.
