About Me

Hi, I am Xinkai Wang. Currently, I am a postdoctoral researcher in the School of Computer Science, Shanghai Jiao Tong University, working with Prof. Minyi Guo. I received my Ph.D. from Shanghai Jiao Tong University in 2026, advised by Prof. Chao Li. I was a visiting scholar at Ghent University, advised by Prof. Lieven Eeckhout. I received my bachelor’s degree with Zhiyuan honors from Shanghai Jiao Tong University in 2021.

My research area is computer architecture and systems, with a primary focus on efficient and resilient AI infrastructure. I am currently interested in energy-efficient design exploration for agentic AI infrastructure and agentic management for highly-resilient infrastructure. If you are interested in my project details and further collaborations, feel free to contact me. Here is my Curriculum Vitae.
