Michael Elmhirst Cates FRS FRSE (born 5 May 1961) is a British physicist. He has been the 19th Lucasian Professor of Mathematics at the University of Cambridge since 1 July 2015. He was previously Professor of Natural Philosophy at the University of Edinburgh, and has held a Royal Society Research Professorship since 2007. His scientific work is varied, but focuses on the theory of soft matter, such as polymers, colloids, gels, liquid crystals, and granular material. A frequent goal is to create a mathematical model that predicts the stress in a flowing material as a functional of the flow history of that material. Such a mathematical model is called a constitutive equation. Recently he has worked on theories of active matter, particularly dense suspensions of self-propelled particles which can include motile bacteria. He is increasingly interested in fundamental field theories of active systems in which time-reversal symmetry (T-symmetry, and more generally CPT symmetry) is absent. Such theories are characterized by nonzero steady-state Entropy production. Another recent interest is the flow of shear-thickening suspensions such as dense solutions of corn-starch or custard powder in water; this work was presented in a recent public lecture.
