I am a final-year Ph.D. student at MIT advised by Armando Solar-Lezama. I received my bachelor's degree from Harvard in 2008. My research interests are in programming language design, software verification, and privacy and security.
My research is about designing language constructs and execution strategies that allow the runtime to take responsibility for tedious, error-prone tasks that cut across the program. For my Ph.D. thesis I have created a programming language, Jeeves, for automatically enforcing information flow policies for privacy and security. I am building a web framework that extends the programming model in database-backed applications.
To increase the impact of security research, I started The Cybersecurity Factory, a summer program for security startups, with fellow MIT PhD student Frank Wang. We are running a pilot program in Cambridge, MA this summer.
- Jeeves, a language I created for automatically enforcing security and privacy policies.
- Verve (on Wikipedia), an operating system I built with Chris Hawblitzel automatically verified end-to-end for type safety. This work won Best Paper Award at PLDI 2010.
- Ask Reeves, a verifier I built for privacy policies at Facebook. The details of this work are not public but I filed a patent in 2013 and am happy to talk about it.
- F*, a language for secure distributed programming using dependent types.
- I also collaborate with the developers of the Julia language for scientific programming.

Relevant Activities and Links.
In spring 2010, I started the annual MIT Programming Languages Offsite Meeting for exchanging ideas among MIT research groups in programming languages, software engineering, and human-computer interaction.
In fall 2009, I co-founded Graduate Women at MIT for the promoting the personal and professional development of graduate women. I also created the Positivity@MIT project for creating a more positive workplace environment.
As of fall 2013, I have been co-directing NeuWrite Boston, a collaborative working group for scientists and writers, with Amanda Gefter. Our goal is to improve and innovate the state of science communication.
I also have a couple of satirical photo blogs. My brogramming project examines the "brogrammer" trope in tech culture and also society's image of the programmer. My Strong Reject meme satirizes the human aspects of the scientific reviewing process. There is also Haskell Ryan Gosling, an exercise in discovering how much Haskell can be taught through Ryan Gosling.
