I am a research associate in the Laboratory for Foundations of Computer Science, one institute of the School of Informatics at the University of Edinburgh. I work on implementation and interpretation of session types for the ABCD project, along with Phil Wadler and Sam Lindley.
Most recently, I was a Ph.D. student in the computer science department at Portland State University, advised by Mark P. Jones. As part of the High Assurance Systems Programming project, I contributed to the design of the Habit programming language, particularly its class system, and to the development of the Habit compiler, particularly its typechecking and desugaring components.
