I am seeking applications for a post-doctoral scholar at the University of Iowa, starting in Summer of 2024. We study extensibility and modularity in high-level typed functional programming languages, particularly Haskell. The post-doctoral scholar will contribute to an NSF-funded project exploring a new semantic foundation for type classes and type families in Haskell. Their work may include formalizing the new approach in Agda, implementing it in GHC, and evaluating that implementation. Position A PhD in computer science or a closely related field, with a strong background in programming languages and logic, is required. The ideal candidate would also have: - Knowledge of and experience with Haskell programming, including the use of type classes and type families - Experience with mechanized theorem proving in Agda - Good English writing and speaking skills - Ability to work in a collaborative environment - A strong commitment to research excellence This is a one year position with a starting salary of $58,179, but may be extended for up to two additional years based upon performance and the continued availability of funding. The position will start in Summer 2024 (or as soon as possible thereafter), and will remain open until filled. To apply, or with questions about the position, please email Garrett Morris <garrett-morris@uiowa.edu> with your CV (including a list of publications), a brief letter explaining your suitability for the rule, and the names of at least two references. Computational Logic Center The post-doctoral scholar will join the Computational Logic Center (CLC) within the department of computer science. The CLC performs research across programming languages, formal verification, and automated reasoning, and includes J. Garrett Morris (https://jgbm.github.io), Cesare Tinelli ( https://homepage.cs.uiowa.edu/~tinelli/), Katherine Kosaian ( https://sites.google.com/view/katherinekosaian), as well as several research scientists, post-doctoral scholars, and graduate student researchers. The scholar will have the opportunity to collaborate with other CLC members, as well as participating in joint seminars and other activities.
