Ruichun Ma | Yale University

About Me

I am a senior researcher at Microsoft Research Asia - Vancouver, working on next-generation wireless systems, Embodied and Agentic AI.

I completed my PhD study at Yale University, advised by Wenjun Hu and Lin Zhong. I also worked closely with Lili Qiu at MSRA Shanghai. During my PhD, I worked on building metasurface-based wireless systems and received ACM SIGMOBILE Doctoral Dissertation Award.
