Jeremy Siek is an Associate 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 Advocate for gender equity.
I’ve been fortunate to see some of my ideas get used in the software industry:
- Facebook has added gradual typing to PHP. See the article in Wired magazine.
- The implicits feature of Scala was inspired by my work on concepts for C++.
My group’s research is currently funded by the following sponsors.
- The National Science Foundation awarded the following projects:
- Facebook is supporting us through a Faculty Research Award.

CS MS Student Advising
I am available for walk-in advising in my office (Luddy 3016) on every Monday and Friday at 11AM-noon during the Spring 2018 semester. If you have a question about fulfilling your MS degree requirements, prior to coming to my office, send me an email with a list of your courses organized by how they fulfill the degree requirements. Each course should be listed only a single time. The subject line of the email should be “CS MS:”. Students who have followed these instructions will be prioritized over students who have not. If you cannot make it to the walk-in time, you may also send me email, and I will read and respond to those emails during the walk-in advising time, but giving priority to students who are there in person.
Information for Students at IU

- What are the requirements for a CS MS degree?
- What are the requirements for a CS PhD degree?
