James Anthony Dominic Welsh(known professionally asD.J.A. Welsh) (born 29 August 1938, died 30 November 2023[1])[2][3]was an Englishmathematicianand emeritus professor ofOxford University'sMathematical Institute.He was an expert inmatroidtheory,[4]thecomputational complexityofcombinatorial enumeration problems,percolation theory,andcryptography.
Biography
[edit]Welsh obtained his Doctor of Philosophy from Oxford University under the supervision ofJohn Hammersley.[5]After working as a researcher atBell Laboratories,he joined the Mathematical Institute in 1963 and became a fellow ofMerton College, Oxfordin 1966. He chaired the British Combinatorial Committee from 1983 to 1987.[3]Welsh was given a personal chair in 1992 and retired in 2005.[3]He supervised 28 doctoral students.[6]
