Principles of Programming Group

Computer Science Department

Carnegie Mellon University

What We Do

The goal of the PoP group is to understand, develop, and demonstrate the principles, processes, and supporting technologies for the construction of computing systems.

Special areas of interest include: applications of logic (including formal semantics and type theory); techniques for designing and implementing programming languages; formal specification and verification of hardware and software systems.

A distinguishing characteristic of the PoP group is that it applies formal principles to problems of realistic scale and complexity, for example: automatic verification of large-scale commercial hardware systems; implementation of high-speed network communication software in the ML language; application of type-theoretic principles in the construction of realistic compilers.
