Biography

I am working with Chris J. Rossbach on fundamental and practical virtualization problems. My previous and current researches and project experience cross different boundaries: from electronics to computer science; from stand-alone server to cloud services; from user-space to kernel-space; from virtual machine to hypervisor; from compiler to software system.
