Dr Timothy Reis BSc (Hons), MSc, PhD, FIMA

Timothy Reis is Head of School for Computing and Mathematical Sciences and an applied mathematician whose research is internationally recognised in the theory and application of the lattice Boltzmann method (LBM). His work has made significant contributions to the mathematical and kinetic foundations of LBM, particularly in the development of multiphase flow models and boundary conditions, including extensions to the slip‑flow regime.  His research has been published in leading journals including SIAM Journal on Scientific Computing, Journal of Computational Physics, Journal of non-Newtonian Fluid Mechanics, and Physics of Fluids, and is widely cited within the computational fluid dynamics and applied mathematics communities.  He has enjoyed visiting fellowships to the Issac Newton Institute and the Beijing Computational Science Research Centre, and his doctoral work on "The Lattice Boltzmann Equation for Complex Flows" won the Vernon Harrison Prize from the British Society of Rheology for the most distinguished thesis.

Alongside maintaining an active research profile and supervising doctoral researchers, Dr Reis provides strategic academic leadership as Head of the School of Computing & Mathematical Sciences.  In his previous role as Academic Portfolio Lead for Mathematics, he led a major redesign of Greenwich’s mathematics provision, developing a distinctive, theme‑based degree structure grounded in real‑world societal, scientific, and business challenges. This work was nationally recognised through the award of a CaMS Project Award (Campaign for Mathematical Sciences), supporting the development of an innovative new mathematics degree and contributing to widening participation and re‑imagining pathways into mathematical sciences education.
