Samson Abramsky FRS FRSE (born 12 March 1953) is Professor of Computer Science at University College London. He was previously the Christopher Strachey Professor of Computing at Wolfson College, Oxford, from 2000 to 2021.

Abramsky's early work included profound contributions to domain theory and the connections thereof with geometric logic. Since then, his work has covered the lazy lambda calculus, strictness analysis, concurrency theory, interaction categories and geometry of interaction, game semantics and quantum computing. Notably, he co-pioneered categorical quantum mechanics. More recently, he has been applying methods from categorical semantics to finite model theory, with applications to descriptive complexity.

Education

Abramsky was educated at Hasmonean Grammar School for Boys, Hendon and at King's College, Cambridge (BA 1975, MA Philosophy 1979, Diploma in Computer Science) and Queen Mary, University of London (PhD Computer Science 1988, supervised by Richard Bornat).

Career and research

Since 2021, Abramsky has been Professor of Computer Science at University College London. He has been a Fellow of the Royal Society since 2004. His research includes the development of game semantics, domain theory in logical form, and categorical quantum mechanics.

His earlier positions include:

• Programmer, GEC Computers Limited, 1976–1978
• Lecturer, Department of Computer Science and Statistics, QMUL, 1980–1983
• Lecturer, 1983–1988, reader, 1988–1990, professor, 1990–1995, Department of Computing, Imperial College London
• Professor of Theoretical Computer Science, University of Edinburgh, 1996–2000
• Christopher Strachey Professor of Computing, University of Oxford, 2000–2021

Abramsky has played a leading role in the development of game semantics, and its applications to the semantics of programming languages. Other notable contributions include his work on domain theory in logical form, the lazy lambda calculus, strictness analysis, concurrency theory, interaction categories, and geometry of interaction. He has recently been working on high-level methods for quantum computation and information.

Abramsky's nomination for the Royal Society reads:

Samson Abramsky is distinguished for seminal contributions to the mathematical foundations of computation. His outstanding achievement is his development of Game Semantics as a theory of computational processes which exposes the mathematical structure of the information flow between them. This has led to powerful applications in the study of programming languages, offering decisive new insights into the nature of sequentiality, state, control, and many other computational features. It is now leading in turn to new developments in computer-assisted program analysis and verification. An important strand, which also stands as a contribution to logic, is a generalisation of Girard's Geometry of Interaction, leading to a new genre of full completeness theorems, which characterise the 'space of proofs' of a logic. Previously, Abramsky made important contributions to abstract interpretation, domain theory, lambda calculus and concurrency. He continues to shed light over a broad range of topics by sharp and creative insights, breaking new ground, and bringing order and unity to existing work.
