Vic Shihang Li's profile picture.

Vic Shihang Li

I build agents that autonomously design and operate systems end-to-end, and the systems that run those agents quickly, reliably, and securely.

I'm Vic, a third-year CS PhD at UW, advised by Simon Peter and Tom Anderson, and affiliated with SysLab, FOCI and SyFI.

I co-lead the Self-Defining Systems initiative, which asks how systems should be built when agents drive the end-to-end work: specification, design, implementation, and operation. Before agents, I built systems across the stack, from hardware abstractions to software runtimes. More in my research page and resume.

Before UW, I worked with Malte Schwarzkopf as an MS student at the ETOS group at Brown. Before that, I studied Finance and CS at NYU Stern.

Teaching & Service

Mentoring

Mentoring students is one of the most rewarding parts of my work. I work with many talented students. See here for who they are and what they work on.

I am always looking for talented undergraduate or MS students to work with. If my research looks interesting to you, reach out to me via email.

Teaching

I am also an instructor for CSE 492R @ UW, a program that makes research more accessible to undergraduates, where I mentor students on a project tied to my research.

Service

  • Pre-PhD applicant mentor for the 2024 cycle, via the PAMS program at UW CSE.
  • Mentor for first-year PhD students in the 2024-25 academic year.
  • Member of EuroSys '25 Shadow PC.
