This winter I am teaching CSE 341 (Programming Languages). Check out the course webpage! —December 30, 2016
I am a fourth year PhD student in the Computer Science and Engineering department at the University of Washington. My interests are in programming languages and applications of PL techniques to systems. I'm also a sucker for math, music, and puzzles.
I'm advised by Zach Tatlock in the Programming Languages and Software Engineering (PLSE, pronounced "pulse") group. I am grateful to be supported by a National Science Foundation Graduate Research Fellowship.
I graduated from Williams College in 2013 with a lot of great friends as well as a B.A. in Computer Science and Mathematics. I did research with Steve Freund (Summer 2012, Fall 2012, and Spring 2013) and Duane Bailey (Winter 2011). In summer 2013, I worked for NVIDIA as an intern in the research division under David Luebke and Morgan McGuire.
Outside CS, I enjoy coffee, music, bicycling, and reading. My favorite Seattle coffee shops these days are Roy Street in Capitol Hill and Allegro in the U district. The PLSE lab comes in a close third.
I sing in the UW Chamber Singers, the St. Marks Cathedral Choir, and the Compline Choir.
The Chamber Singers were excited to perform at the ACDA Northwest conference in March, 2014. You can see videos of our performance here, here, here, and here. We are also working on a CD with repertoire from the 2013-2014 and 2014-2015 seasons. The Cathedral Choir performs each Sunday at 11am at St. Marks.
The Compline Choir performs each Sunday night at 9:30pm at St. Marks. The compline service a 30 minute chanted/sung service that tends to draw hundreds of people every week and thousands via a live radio broadcast and the podcast. It's a classic Seattle experience. You should check it out! You can listen live on King FM or get the podcast.
I occasionally play handbells.
Finally, I like to ride my 2009 Trek 520 bicycle: in 2009 I biked the TransAm. I bike from Ballard to CSE most days on the Burke-Gillman. I'm thinking about buying a mountain bike and biking along the Adventure Cycling Great Divide Trail in August 2015.
In non-fiction, I enjoy philosophy and popular science books. I recently read and enjoyed Jonathan Haidt's The Righteous Mind. In fiction, I like short stories and (not exactly fiction) essays by people who write good short stories. Recent favorites include George Saunders' The Braindead Megaphone.
Exercises on Generalizing the Induction Hypothesis. This post collects several Coq exercises on generalizing the induction hypothesis. —February 21, 2017
A Port of the Proof of Peterson's Algorithm to Dafny. This code-only post is a port of the proof of Peterson's Algorithm to Dafny. It also serves as a good example of how to reason about concurrent systems in Dafny, essentially by writing a thread scheduler. —January 9, 2017
How to build a simple system in Verdi. In this long-awaited post, we'll show how to implement and verify a simple distributed system using network semantics. —April 24, 2016
A Proof of Peterson's Algorithm. In this post, we take a break from distributed systems to look at shared memory systems. As a case study, we give a proof that Peterson's algorithm provides mutual exclusion. —May 8, 2015
Network Semantics for Verifying Distributed Systems. This is the first post in a series on Verdi. In this post, we'll get our feet wet by defining a formal model of how distributed systems execute on the network. —April 16, 2015
Reasoning about Cardinalities of Sums and Products. In this short, code-heavy post, we extend some of the work from a previous post to reason about the cardinalities of sums and products. —October 20, 2014
Dependent Case Analysis in Coq without Axioms.
This post shows how to get around the limitations of
destruct tactic when doing case analysis on dependent
types, without resorting to the
dependent destruction tactic,
which relies on additional axioms.

"run" + "time" = ???. This brief post records Mike's description of the three ways of combining the words "run" and "time" in computer science writing. —September 4, 2014
"More Sums than Differences" Sets, Part 2: Counting MSTD Sets. This is the (much delayed) second post in a series on More Sums than Difference Sets. In this post, we'll take a first crack at the question, "How many MSTD sets are there?" To do so, we'll write a straightforward C program that counts MSTD sets. Then we'll run it to count MSTD sets and benchmark its performance. —June 12, 2014
Tail Recursion Modulo cons. Tail recursion has come up in a few conversations this week. This post explores a generalization of tail call optimization that I wasn't aware of until Doug described it to me. —April 10, 2014
"More Sums than Differences" Sets, Part 1: A puzzle. This is the first post in a series on "More Sums than Differences" Sets. In this post, we'll get our terminology straight and ask a lot of questions. —March 3, 2014
Easy access to the off-campus proxy. I use the UW proxy to access the ACM digital library from off campus, but it's annoying to type the proxy URL every time I click a link to a new paper. Here are two ways to make life easier. —December 31, 2013
I've had the pleasure of working with the following undergraduates at UW:
In winter '17, I am teaching CSE 341 (Programming Languages). Check out the course webpage!
In fall '13, I TAed CSE 505: Programming Languages with Zach Tatlock.
I have helped run the following reading groups:
