Stephanie Weirich (/ˈwaɪərɪk/ WYRE-ik[1]) is an American computer scientist specializing in type theory, type inference, dependent types, and functional programming. She is a professor of computer science at the University of Pennsylvania.
Weirich graduated magna cum laude in 1996 from Rice University, with a bachelor's degree in computer science.[2] At Rice, she became interested in programming languages through an undergraduate research project with Matthias Felleisen.[3] She moved to Cornell University for her graduate studies, completing her Ph.D. in 2002.[2] Her dissertation, Programming with Types, was supervised by Greg Morrisett.[4] She joined the University of Pennsylvania faculty in 2002.[2]
Weirich's work on type inference has been incorporated into the Glasgow Haskell Compiler. She has also been a leader of the POPLmark challenge for benchmarking type systems of programming languages. Weirich won the SIGPLAN Robin Milner Young Researcher Award in 2016.
