J. Roger Hindley is a prominent British logician best known for the Hindley–Milner type inference algorithm. Since 1998, he has been an Honorary Research Fellow at Swansea University.^[1]

Hindley graduated in 1960 from Queen's University Belfast, remaining to earn an M.Sc. in 1961.

He went on to receive a Ph.D. in 1964 from the University of Newcastle upon Tyne, where his thesis supervisor was Ronald Harrop. Later, he returned to Queen's University for a D.Sc. in 1991.

He taught at Penn State University (1964–1966), Bristol University (1966–1968), and has been at Swansea University since 1968.
