Miscellaneous

Thesis

I defended my thesis, "Lightweight verification of functional programs" [pdf], in May 2013. You can find extended versions of many of my publications in it.

Summary: there’s no point proving a program correct without testing it first, because a) the program will have bugs and b) the specification will have bugs. Let’s bring proof and testing closer together! If we write testable specifications, we can move smoothly between the two.

Teaching

I teach the Data Structures course for GU students in period 4.
