Research Interests

Professor Phillips’s research interests include numerical analysis, spectral methods, computational fluid dynamics and rheology. He is an international authority on high-order discretization methods for solving problems in computational fluid dynamics, especially with respect to problems in rheology. He has written over one hundred research articles and contributions to conference proceedings. His first book, Computational Rheology, was published by Imperial College Press in 2002. His research activities have generated substantial funding from EPSRC, EU and Industry. He is one of the principal investigators in an EPSRC funded Portfolio Partnership in the area of Complex Fluids and Complex Flows, which is an interdisciplinary research network involving chemical engineers and computer scientists at Swansea University. He is a member of the EPSRC College and Membership Secretary of the British Society of Rheology.
