Nick Britton worked at the crossover between biology and maths SuzanneSkevington Fri 30 Apr 2021 07.24 EDT Last modified on Fri 30 Apr 2021 07.26 EDT My husband, Nicholas Britton, who has died aged 67 of bone cancer, was a pioneering mathematical biologist whose research covered a huge range of subjects, from how malaria is transmitted to the growth of tree rings, and dialects in bird song. His teaching and work on modelling techniques made an important contribution to inspiring and training the generation of researchers who are currently applying these skills and knowhow to solving the problems of the Covid-19 pandemic. Nick was born in London, to Barbara Ferris, a teacher, and Geoffrey Britton, a university lecturer in medieval English. Sunday lunch was punctuated by debates about seemingly obscure facts. At Haberdashers’ Aske’s school, Nick developed his mathematical talent and also enjoyed Russian and learning to play the clarinet. With a scholarship, he studied mathematics at Corpus Christi College, Oxford, where he played bridge and rowed, graduating in 1975. Completing a DPhil in two years, he won the university’s prize for the best DPhil in 1978.
