Andrew D. Gordon is a British computer scientist employed by Microsoft Research. His research interests include programming language design, formal methods, concurrency, cryptography, and access control.
Gordon earned a Ph.D. from the University of Cambridge in 1992. Until 1997 Gordon was a Research Fellow at the University of Cambridge Computer Laboratory. He then joined the Microsoft Research laboratory in Cambridge, England, where he is a principal researcher in the Programming Principles and Tools group. He also holds a professorship at the University of Edinburgh.
Gordon is one of the designers of Concurrent Haskell, a functional programming language with explicit primitives for concurrency. He is the co-designer with Martin Abadi of spi calculus, an extension of the π-calculus for formalized reasoning about cryptographic systems. He and Luca Cardelli invented the ambient calculus for reasoning about mobile code. With Moritz Y. Becker and Cédric Fournet, Gordon also designed SecPAL, a Microsoft specification language for access control policies.
