Dr Armando Coco
Lecturer in Mathematical Modelling
I joined the Oxford Brookes University as a Lecturer in Mathematical Modelling in September 2015. I obtained a Ph.D. in Mathematics for Technology in Catania (Italy) in 2012 and I held a postdoc Research Assistant position at INRIA (France), at University of Bari (Italy) and at University of Bristol.
I have always been passionate for Mathematics in a broad sense, from the rigorous theory to real-life oriented applications, as well as teaching at different levels, from secondary Schools to postgraduate level. Related to my area of expertise, I have a substantial experience in numerical methods for applied mathematics, since this has been the field of my research since my doctorate studies. The interdisciplinary aspects of my research allow me to combine the analytical rigorous thinking developed since my undergraduates studies in Pure Mathematics with the technical expertise of an Applied Computational Mathematician.
Finding a perfect harmony between research and teaching and achieving this goal also by integrating my research projects into teaching programmes is at the base of my job philosophy.
I am the module leader for:
- U04520 Engineering Mathematics
- U08604 Modelling and Computation
Memberships and affiliations:
- UMI (Italian Mathematical Union), since 2009
- GNCS (National Group of Scientific Computing, Italy), since 2009
- AGU (American Geophysical Union), since 2014
Although I am interested in many aspects of Mathematics, my research activity is focussed on the design of highly efficient and accurate numerical models for problems involving fluid mechanics and elastic deformation in order to simulate and possibly predict some complex phenomena coming from geophysics and scientific engineering for academic and industrial applications. I am interested in devising general methods that account for complex (possibly moving) geometries, implicitly described by level-set methods, and designing specific multigrid solvers. Particular interest is devoted to stationary problems, either in general form (elliptic equations) or specific to an application field (Cauchy-Navier equations for Linear Elasticity in Volcanology problems, Stokes equations for steady-state behavior of incompressible fluid dynamics). A recent interest is time-dependent equations and moving boundary/interface governing fluid mechanics, with particular attention to incompressible fluid dynamics, fluid flow in porous media, compressible gas dynamics.
