Judith Patricia Armitage FRS (born 1951) is a British molecular and cellular biochemist at the University of Oxford.


She attended Selby Girls' High School, an all-female grammar school, then located in the West Riding of Yorkshire. In her sixth form, the school became the co-educational Selby Grammar School.

Armitage was educated at University College London, and was awarded a PhD in 1976 for research on the bacterium Proteus mirabilis.[2]


Armitage's research is largely based on the motion of bacteria by flagellar rotation and the chemotactic mechanisms used to control that motion.[3] Armitage has been based in Oxford since 1985 and was awarded the Title of Distinction of professor of biochemistry in 1996. Armitage is a fellow of Merton College, Oxford[4] and the director of the Oxford University Centre for Integrative Systems Biology.[5][6][7][8]

Awards and honours[edit]

Armitage was elected a Fellow of the Royal Society (FRS) in 2013. Her nomination reads:[1]

Judith Armitage is distinguished for pioneering contributions to the understanding of spatio-temporal complexity and cellular organisation in bacteria. Combining biophysics and in vivo light microscopy with molecular genetics she discovered a new protein partitioning system that exerts spatial control over sensory signalling pathways. Co-crystal structural studies of a sensory kinase and its cognate response regulator directly revealed single amino acid changes involved in pathway discrimination. The first direct measurements of the dynamics of rotor and stator proteins in rotating flagellar motors revealed exchange with free protein pools, an observation which fundamentally changed our understanding of bacterial motility and behaviour.
