My research focuses on directly applying formalism to practical problems. Much of my work takes place in the emerging field of semantics engineering, where I scale PL techniques up to work on real systems.
My primary focus is on improving the POSIX shell and building tools to support its use.
I work in a variety of other areas: contracts and gradual types; tools for directly expressing PL formalism, using logic programming and SMT solving; and foundational semantics for decidable languages, like Kleene algebra with tests.

I got a BA in Computer Science and Egyptology from Brown University (2007) and a PhD in Computer and Information Science from the University of Pennsylvania (2013). I did a postdoc with Dave Walker at Princeton (2013–2015), after which I was an assistant professor at Pomona College (2015–2021) before moving to Stevens Institute of Technology (2021). I visited Steve Chong in a scholarly way at Harvard University (2018–2019).
