Hello!
I am a Researcher at Microsoft Research. I do research on the boundary between computer architecture and computer systems. My research focuses on improving programmability, reliability, and efficiency of computing.

My current research projects address these issues along several different dimensions. I am working to define a reasonable system stack - from the application to the architecture - for low-/no-power computing devices that harvest energy from their environment, experiencing power failures as common case behavior. I am looking at how to reconcile programmability, performance, and generality in heterogeneous computing systems (e.g., CPU + GPU + FPGA), with an emphasis on defining a useful memory model for such systems. I am also looking at ways of making concurrent programs correct and reliable that require minimal involvement from a programmer by taking advantage of statistical inference and symbolic execution. In my prior work, I have worked on defining new concurrent programming models, inventing better architecture support for concurrency debugging, and building systems and architectures that automatically avoid failures in broken concurrent programs.

Broadly, I like working on architectural features and systems that make life easier during development and remain useful throughout a system's lifetime. I prefer to work across the layers of the system stack - hacking the os, language features, tool support, microarchitecture, etc. I think statistical methods and inference, empirical systems, and systems that dynamically adapt their behavior are all really cool and those kinds of things show up in my research projects.

I got my Ph.D. in Computer Science and Engineering from the University of Washington in 2013. I was advised by Luis Ceze. My Ph.D. dissertation is available here.

My publications are available on Google Scholar and in the list below.

News
I gave a talk at the 2014 MSR Faculty Summit on my work with Ben Ransford on programming intermittently powered devices. I spoke in the Impossibly Small Devices Session and my slides are here.

Jie Liu, Desney Tan, Arjmand Samuel, and I co-organized the Microsoft Research Ultra-low-power Computing Workshop. The event was colocated with the MSR Faculty Summit. We had great speakers and attendees and the event was a real success!

Ben Ransford and I wrote a short paper on some really cool design problems that show up in intermittently powered computers. It will appear at MSPC this year, which is colocated with PLDI.

Check out the just-accepted Approx 2014 workshop paper on system support for automatic program specialization that Todd Mytkowicz and I wrote!

Joe Devietti and I are organizing the 2014 Workshop on Determinism and Correctness in Parallel Programs (WoDet 2014), which is co-located with ASPLOS 2014 in Salt Lake City. You should consider submitting a paper! [Update: WoDet was a success! Lots of attendees, great discussions and awesome keynotes by Dean Tullsen (@UCSD) and Brian Lewis (@Intel Labs).]

I am working with a group from MSR on an open session at ICTD 2013 on creating software on mobile and touch-based devices using TouchDevelop.

In June 2013, I finished my Ph.D. and I've got a job at Microsoft Research!

Aviso, our latest paper about making systems cooperate to avoid concurrency-related failures, will appear at ASPLOS 2013!
