Research Themes

PL for Social Good

We invent usable programming tools to help teams working for social good—social scientists, journalists, lawyers, domain experts focused on marginalized groups. (Working for social good and struggling to write code or process data? Get in touch!)

PL+HCI

We combine techniques from Programming Languages and Human-Computer Interaction to make programming languages and programming tools that work better for coders and non-coders alike.

How Statically-Typed Functional Programmers Write Code

How Statically-Typed Functional Programmers Write Code

How Statically-Typed Functional Programmers Write Code on ACM DLHow Statically-Typed Functional Programmers Write Code on Youtube

A grounded theory (and experimental validation) of how statically-typed functional programmers write code, covering domain modeling, type construction, focusing techniques, exploratory strategies, mental models, and expressions of intent.

Understanding Version Control as Material Interaction with Quickpose

Understanding Version Control as Material Interaction with Quickpose

Understanding Version Control as Material Interaction with Quickpose on GitHubUnderstanding Version Control as Material Interaction with Quickpose on ACM DLUnderstanding Version Control as Material Interaction with Quickpose on Youtube

A version control tool for creative programmers. We used this tool to study how people use different versions of their programs in their process—navigating between, annotating and arranging, and backtracking to previous versions of their programs.
