Les Hatton (born 5 February 1948) is a British-born computer scientist and mathematician most notable for his work on failures and vulnerabilities in software controlled systems.

He was educated at King's College, Cambridge 1967–1970 and the University of Manchester where he received a Master of Science degree in electrostatic waves in relativistic plasma[1] and a Doctor of Philosophy in 1973[2] for his work on computational fluid dynamics in tornadoes.

Although originally a geophysicist, a career for which he was awarded the 1987 Conrad Schlumberger Award[3] for his work in computational geophysics, he switched careers in the early 1990s to study software and systems failure.

Primarily a computer scientist nowadays, he retains wide interests and has published recently on artificial complexity in mobile phone charging, the aerodynamics of javelins and novel bibliographic search algorithms for unstructured text to extract patterns from defect databases.

[13] After spending most of his career in industry working for Oakwood Computing Associates,[14] he is currently a professor of Forensic Software Engineering at Kingston University, London.
