Jeremy Siek is an Associate Professor at Indiana University Bloomington. Jeremy teaches courses on programming, algorithms, compilers, logic, and mathematics. Jeremy's interests include generic programming, programming language design, type systems, and high-performance programming. Jeremy's Ph.D. thesis laid the foundation for constrained templates, aka the "concepts" proposal for C++. Prior to that, Jeremy developed the Boost Graph Library, a C++ generic library for graph algorithms and data structures. Jeremy post-doc'd at Rice University where he developed the idea of gradual typing: a type system that integrates both dynamic and static typing in the same programming language. Jeremy is currently working on a gradually-typed version of Python, a language for reflective meta-programming, a version of concepts for Chapel, and a domain-specific compiler for generating memory-efficient linear algebra kernels. In 2009 Jeremy received the NSF CAREER award to fund his project: "Bridging the Gap Between Prototyping and Production". In 2010 Jeremy was awarded a Distinguished Visiting Fellowship from the Scottish Informatics & Computer Science Alliance.
