Colin J. Bushnell

Colin John Bushnell (1947 – 1 January 2021) was a British mathematician specialising in number theory and representation theory. He spent most of his career at King's College London, including a stint as the head of the School of Physical Sciences and Engineering, and made several contributions to the representation theory of reductive p-adic groups and the local Langlands correspondence.

Early life and education Bushnell was born in 1947. He studied mathematics at King's College London, where he received his first class honors undergraduate degree and then a Ph.D. in 1972 under the supervision of Albrecht Fröhlich. From 1996 to 1997, he was a chairman of the mathematics department and from 1997 to 2004 he was the head of the School of Physical Sciences and Engineering.

Research Bushnell's research included "major contributions to the representation theory of reductive p-adic groups and the study of the local Langlands correspondence."
