John Martin Rallison

John Martin Rallison is a Professor in the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge. His research focuses on fluid mechanics, particularly the behavior of non-Newtonian fluids, polymer solutions, and viscoelastic flows. He has contributed extensively to understanding phenomena such as droplet dynamics, suspension mechanics, and instabilities in complex fluids. His work often employs computational methods and analytical models to study transient flows, capillary effects, and microstructural interactions.

Key areas of research include the deformation of viscous drops in shear flows, coextrusion instabilities of elastic liquids, and the rheology of dilute polymer solutions. He has also explored topics like dynamic light scattering in suspensions and the physics underlying constitutive equations for complex fluids.

Professor Rallison’s publications span over four decades, reflecting his deep engagement with fundamental and applied aspects of fluid dynamics. His work is characterized by rigorous mathematical modeling and interdisciplinary applications in engineering and materials science.
