Hi! I am Zhiwei, a fourth-year Ph.D. candidate in Statistics at University of Michigan, Ann Arbor, gratefully advised by Prof. Wei Hu and Prof. Yixin Wang. My research interest is centered around theoretical and scientific understanding of foundation models.
Recently I'm interested in designing more efficient model architecture and more effective training strategies for agentic models. Feel free to reach out if you share the same interests!
