Ph.D. Candidate of Computer Science

Stony Brook University

Biography

I am Yifei Liu, a Ph.D. candidate in Computer Science at Stony Brook University . I am part of the File systems and Storage Lab (FSL) , advised by Prof. Erez Zadok . I am broadly interested in file/storage systems and operating systems. My recent work seeks to test kernel file systems more readily and thoroughly by model checking and other related techniques.

Before Stony Brook, I was a Master’s student and research assistant at the Wuhan National Laboratory for Optoelectronics , advised by Prof. Ke Zhou , at Huazhong University of Science and Technology . There, I focused on the integration of content-based semantic queries in storage systems.
