Jeremy Siek is a Professor of Computer Science in the School of Informatics and Computing at Indiana University. Jeremy teaches courses in programming, programming languages, compilers, logic, and other areas of computer science. Jeremy designs new language features to help programmers create and use software libraries and domain-specific languages, especially generic and high-performance ones. In particular, with Walid Taha, Jeremy invented the gradual typing approach to mixing static and dynamic type checking within the same language. Prior to that, Jeremy co-authored the Boost Graph Library and attempted to add concepts to C++. Jeremy is a member of the Center for Programming Systems at IU and Jeremy is an Ally for gender equity.

Books

  • The Boost Graph Library (ebook from Pearson, print from Amazon)
  • Essentials of Compilation (Racket version: complete draft pdf and available for pre-order for the February 2023 release date from MIT Press, Python version: complete draft pdf and also available for pre-order, release date of August 2023)

Upcoming: I’ll be giving a tutorial on Teaching and Learning Compilers Incrementally at PLDI 2023.

Technology Transfer

I’ve been fortunate to see some of my ideas get used in the software industry:

  • Microsoft created a gradually-typed dialect of JavaScript, called TypeScript.
  • Facebook has added gradual typing to PHP. See the article in Wired magazine.
    Facebook has also created Flow, a static type checker for JavaScript.

Sponsors

My group’s research is currently funded by the following sponsors.
