About

I'm a Senior Researcher in the Networking Research Group at Microsoft Research Redmond. I completed my Ph.D. in Computer Science at Stanford University, advised by Keith Winstein. My research focuses on creating new systems and abstractions for large-scale interactive computing, where users can execute a wide range of resource-intensive tasks with low latency.

My recent work includes:

• R2E2, a system for path tracing massive scenes using a “supercomputer” constructed on-the-fly,
• gg, a framework for outsourcing everyday jobs to 10,000 threads on serverless platforms,
• Salsify, a new architecture for low-latency real-time Internet video, and
• ExCamera, a system for low-latency video processing using thousands of tiny threads.

You can read more about these projects here.
