He was a professor first at University College, Bangor and then at University College in London, eventually rising to the rank of dean at each. He was elected as a Fellow of the Royal Society in 1949.

He collaborated with Christopher Kelk Ingold, leading to development of the eponymous Hughes–Ingold rules and Hughes–Ingold symbols.
