About Me

Hi, I am Xinkai Wang. Currently, I am a final-year Ph.D. student in School of Computer Science, Shanghai Jiao Tong University. I am honored to be guided by Prof. Chao Li in Sustainable Architecture and Intelligence Lab (SAIL) at Institute of Advanced Computing. I received my bachelor’s degree with Zhiyuan honors from Shanghai Jiao Tong University in 2021.

My research focuses on system architecture design with highly-efficient manageability, especially on efficiency-aware management systems and environment-aware management facilities. If you are interested in my project details and further collaborations, feel free to contact me!
