Samson Abramsky (born 12 March 1953) is a British computer scientist who is a 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 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.

Awards and honours Abramsky is a Fellow of the Royal Society (2004), a Fellow of the Royal Society of Edinburgh (2000), and a Member of Academia Europaea (1993). He is a member of the editorial boards of the North Holland Studies in Logic and the Foundations of Mathematics, and of the Cambridge Tracts in Theoretical Computer Science. He was general chair of LiCS 2000–2003, and is a member of the LiCS Organizing Committee.

He was awarded the EATCS Award in 2024 which is given for contributions to theoretical computer science over a life long career. Among his work mentioned in the laudation are his contributions to domain theory, game semantics, and categorical approach to quantum computation and information. He was elected Fellow of ACM (2014) For contributions to domains in logical form, game semantics, categorical quantum mechanics, and contextual semantics. Three of his papers won the LiCS Test-of-Time award (a 20-year retrospective): Samson Abramsky. "Domain theory in Logical Form" (1987). The award was presented at LiCS 2007. Samson Abramsky, Kohei Honda and Guy McCusker. "A Fully Abstract Game Semantics for General References" (1998). The award was presented at LiCS 2018. Samson Abramsky and Bob Coecke. "A categorical semantics of quantum protocols." (2004). The award was presented at LiCS 2024. He was awarded an EPSRC Senior Research Fellowship on Foundational Structures and Methods for Quantum Informatics in 2007. Fellow of the Royal Society (2004) Fellow of the Royal Society of Edinburgh (2000)
