About Me

I am currently a student at UBC, pursuing a PhD in computer engineering under the supervision and support of Sasha Fedorova. I am a member of the Systopia lab which is a loosely-knit group of systems researchers spanning the computer science and electrical engineering departments at UBC.

What I Do

I work on operating systems and related technologies. In the past, I have worked on projects in processing-in-memory, virtualization, file systems and drivers. Currently, I am looking at how to build an operating system from autonomous devices that does not require a CPU. This is part of a larger overall strategy of a mixture of memory-centric computing and accelerator-centric computing. Given that accelerators are performing the bulk of the work in many systems, it makes sense to design the computer infrastructure around the needs of the most used and performance-critical components. The hardware of our computer systems are evolving and the system software must evolve as well to better manage these new hardware designs.

You can see my team's PIM related code on GitHub.
My personal projects are the things I do when I'm not doing the things I'm supposed to be doing. You can see some description on my Personal Projects page.
