Judith Patricia Armitage FRS (born 1951) is a British molecular and cellular biochemist at the University of Oxford.
Armitage earned a BSc in microbiology at University College London in 1972, and was awarded a PhD in 1976 for research on the bacterium Proteus mirabilis.
Her nomination reads:[15] 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.
