Hello! I am a second-year Ph.D. student in Computer Science at Columbia University advised by Asaf Cidon. I am broadly interested in computer systems, especially storage systems, eBPF, memory tiering, and CXL. Before starting my Ph.D., I was a software engineer at VMware in the vSAN group working on vSAN Express Storage Architecture and SplinterDB. I received my master’s degree at Columbia University and my bachelorโ€™s degree at Harbin Institute of Technology.
