Yuxin Yang

PhD student at UCSC

I am a second-year Ph.D. student in the Department of Computer Science and Engineering at the University of California, Santa Cruz, advised by Prof. Yuanchao Xu. My research focuses on computer architecture and systems, with particular interests in secure memory systems, CXL-based memory disaggregation, trusted execution environments, and distributed file systems.

Before joining UCSC, I received my master’s degree from the Wuhan National Laboratory for Optoelectronics at Huazhong University of Science and Technology (HUST), where I was advised by Prof. Fang Wang and Prof. Dan Feng. I also received my bachelor’s degree in Computer Science from HUST.
