He received his PhD in English from Cambridge University  in 1993. He has also taught at both Cambridge and Kyoto Universities. Dr. Constable is a leading scholar of the thought of I. A.

Working with the Japanese physicist, Hideaki Aoyama, Constable also devised and published (in two linked studies on literary and linguistic computing) the first-ever rigorous and mathematical distinction between verse and prose.
