After completing his undergraduate degree in mathematics at Cambridge University, he took an MS at City University, and then worked for ASLIB. He then studied for his PhD at University College London under the renowned statistician and scholar B. C. Brookes. He then returned to City University working there from 1978 until 1998, although he still holds the post of part-time professor in the Department of Information Science. He is also a fellow of Girton College, Cambridge University.
In 1998 he joined the Cambridge branch of Microsoft Research, where he leads a group investigating core search processes such as term weighting, document scoring and ranking algorithms, combining evidence from different sources, and metrics and methods for the evaluation and optimisation of search. Much of his work has contributed to the Microsoft search engine Bing. He has participated a number of times in the TREC conference.
