Interests I'm interested in applying the principles of type theory to the problems of programming language usability. I'm currently working on:
  • VerseML: modularly programmable syntax
  • Tidy: modularly programmable type structure
  • Hazelnut: a bidirectionally typed structure editor calculus
  • A statistical model of typed syntax trees
Past projects include:
  • Wyvern: modularly programmable type-specific syntax
  • Graphite: type-specific interactive code completion (+ user studies!)
  • λRS: a type system for regular string sanitation
I'm also (now only rarely) a theoretical neuroscientist. I've worked on:
  • SciUnit: infrastructure for testing scientific models against data
  • Information-theoretic designs for rehabilitative neural interfaces
  • Dynamical systems models of neurobiological circuits
