I am an associate professor in the School of Computer Science and Engineering, Beihang University (BUAA). I was a postdoc researcher in the Department of Computer Science and Technology, Tsinghua University. I received my PhD degree from Tsinghua University in 2022 (advised by Professor Jiwu Shu and Youyou Lu), and Bachelor degree from Huazhong University of Science and Technology (HUST) in 2017.
My research interests are primarily in storage systems and AI systems, focusing on enhancing their performance and reliability. My work has been published in top-tier conferences and journals on computer systems, including OSDI, SOSP, FAST, USENIX ATC, EuroSys, ASPLOS, HPCA and ACM TOS.
⭐ We are seeking self-motivated Master, PhD, and undergraduate students with strong programming skills to join our research in computer systems and architectures. If you're interested, feel free to reach out with your CV.
