Hi! Bonjour! Привет!

My Head I’m a PhD candidate in computer science at Carnegie Mellon University and a Debian Developer. My professional ambition is to do beautiful mathematics that are relevant to computer science. I’m generally interested in the semantics of programming languages, the Curry-Howard-Lambek isomorphism, parametric polymorphism, and the foundations of mathematics.

While an undergraduate, I had the opportunity to do research at several wonderful places: McGill University, Microsoft Research Cambridge, Queen’s University’s School of Computing, MIT CSAIL, and ENS Lyon. I also spent a semester studying at the Independent University of Moscow in their “Math in Moscow” programme. A copy of my CV is available here.

See my blog for my musings on computer science, mathematics, and languages—spoken or otherwise.

  • Configuring the CMU SCS-Public printer on Linux

    A year ago, I wrote a post on Configuring CMU SCS printers on Linux. SCS Computing Facilities is rolling out a new single-queue print system, where you fetch your job from the queue to a particular printer using your ID card. They don’t provide instructions for configuring this on unfacilitized...
  • Implementing popen and pclose in SML

    Though Standard ML provides the OS.Process.system function to execute an arbitrary command using the default system shell, and the Posix.Process structure for fork and the exec variants, it doesn’t (as far as I know) provide a mechanism to run a process and capture that process’s standard out. I learned from...
  • Presheaf categories are Cartesian closed

    As I’ve been working through “Sheaves in Geometry and Logic”, I’ve been skimming proofs and attempting to rederive them. I normally end up with a better understanding of the material, but sometimes I get stuck. Here’s one case where I’ve gotten stuck: can anybody tell me why the counit for...
  • Configuring CMU SCS printers on Linux

    Unless your Linux host was “facilitized” (i.e., unless you’re still running the stock Linux install provided by the CMU help desk), you’re probably scratching your head as to how to add SCS printers to your Linux host. Here’s how. (NOTE: You should only add SCS printers if you have an...
  • Specifying a custom MTA path in caff

    I recently had to sign someone’s GPG key. I’ve long used the caff tool from the signing-party package to help me with this. Unfortunately, I’m using a new laptop and hadn’t yet configured caff on it. Moreover, caff uses the system MTA by default, normally found at /usr/sbin/sendmail, and I...
