Research interests

I'm advised by Dave Andersen. In general, I'm interested in systems, and especially the line between software and hardware: operating systems, architecture, firmware, embedded systems, and—to some extent—programming languages.

Personal interests

Outside of school, I love bicycling, board games, hiking, bad puns, cooking, rock climbing, trying to speak French, and probably other things that aren't coming to mind at the moment. That's not to say that I'm particularly good at any of those things, though...

In general, please address questions and concerns related to the course to the staff list at 15-213-staff@cs.cmu.edu. Of course, if your message relates specifically to my recitation section or an interaction we had, or if you're looking to schedule an appointment, by all means send it directly to me.

Past projects

Here are the most notable CS-related things I did prior to starting grad school:

Work on coreboot and the Chrome OS firmware

After college, I returned to Google to intern on the Chrome OS Firmware team, where I worked on integrating support for flash maps—roughly the flash chip equivalent to a partition table—into the coreboot project. Most of my work was in the build and bundling tools, and a large portion of my time was spent writing a compiler for our human-readable format for describing flash layouts. cros code upstream code

Work on the Case Bitcoin wallet

At the end of college, I worked at CryptoLabs (now Case Wallet) as a firmware engineer. I did a lot of work on getting the toolchain and debugger working, wrote the first iteration of the build system, and contributed to the overall design of the firmware and the implementation of several of its components. As far as I know, they haven't started open sourcing yet, but their site states that a release is on the way!

Work on the Android Camera app

After my third year of college, I interned on Google's Android Camera Framework team, where I began the process of migrating the AOSP Camera and Google Camera apps to Lollipop's new camera API. My glue code is present in both apps, which come preinstalled on some phones. code

Work on Chrome Remote Desktop

After my second year of college, I interned on Google's Chrome Remote Desktop team, where my task was to port the VNC-like client to Android. As part of the Chromium project, the code is open source, and I posted instructions for compiling your own copy of the Android app. After additional work and polishing by the rest of the team, it was released as a product, and can be downloaded directly from the Play store. app code backend code
