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

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, quantum computing, and probabilistic programming.

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.
