Teng (Sebastian) Jiang

About Me

I’m Teng (though most people call me Sebastian), a Ph.D. candidate in Computer Science at UCLA UCLA , working my way to becoming a savvy system programmer and researcher across the stack. I’m advised by Konstantinos Kallas and Sam Kumar. During my master’s at Columbia University, I worked on several projects, including:

Scheduling for over-subscribed virtual CPUs (vCPUs) at a microsecond time scale. This work was submitted to ASPLOS 2026.
Custom page fault handling with eBPF for use cases like faster VM migration and garbage collection. See publication.

While Sebastian isn’t a name of my heritage, it’s a name I’ve grown attached to (See Why Sebastian?). See my life outside of work here.
