How to pronounce: "Teng" as in "tougue", "Jiang" as "Jee-ang"
About Me
I’m Teng, a Master of Science in Computer Science student at Columbia University, working my way to becoming a savvy system programmer, hacker, and researcher.
My research focuses on advancing the core mechanics of operating systems, with a strong interest in distributed systems, architecture, networking, and the ecosystem of tools that support these areas. Currently, I’m exploring how advancements across the software and hardware stack can enhance the performance and reliability of established technologies such as virtualization and memory management. Some of my ongoing projects are:
- Scheduling for over-subscribed virtual CPUs (vCPUs) at a microsecond time scale. This work was submitted to OSDI 2025.
- Custom page fault handling with eBPF for use cases like faster VM migration and garbage collection. See publication.
I mostly go by Teng, occasionally by Sebastian, a name not of my heritage, but somehow I feel connected to (See Why Sebastian?). See my life outside of work here.
❗️❗️❗️ I’m looking for PhD opportunities in computer systems starting in Fall 2025. Feel free to get in touch through my email: teng.j at columbia dot edu. ❗️❗️❗️
