David Watt (computer scientist)
David Anthony Watt (born 5 November 1946) is a British computer scientist.
Watt is a professor at the University of Glasgow, Scotland. With Peter Mosses he developed action semantics, a combination of denotational semantics, operational and algebraic semantics. He currently teaches a third year programming languages course, and a postgraduate course on algorithms and data structures. He is recognisable around campus for his more formal attire compared to the department's normally casual dress code.
