About Me

Specialist Subjects: Hp Finite Elements, Computational Electromagnetics, Error estimation, Reduced Order Modelling, Efficient Preconditioning, Inverse problems.

Programming and development of H(curl) conforming finite element software capable of hp refinement in two and three dimensions.

Further interests in to the development of preconditioners for indefinite linear systems, inverse problems, uncertainty quantification, a-posteriori error estimation schemes, goal orientated adaptivity, reduced order modelling and novel schemes for reducing dispersion in wave propagation problems.

Applications to problems in computational electromagnetics, including scattering computation, eddy current computation, eigenvalue computation and more recently the modelling of biomedical imaging devices.

Teaching

  • EG-189 Engineering Analysis 1

    This module (in combination with engineering analysis 2) provides the essential grounding in mathematical analysis techniques for engineering students. This module ensures that all students have a suitable level of analytical skills for subsequent engineering modules.

  • EG-190 Engineering Analysis 2

    Module Aims: this module (in combination with Engineering Analysis 1) provides further grounding in mathematical analysis techniques for Engineering students. The module extends the understanding into more complex analytical methods, focusing on complex numbers, multi-variable functions, series and sequences and differential equations.

  • EG-396 Computational Aerodynamics

    This module aims to present a series of numerical methods for simulating aerodynamic flows. The governing equations of fluid dynamics and their simplification for inviscid incompressible irrotational flows will be presented. The finite difference and the finite element methods will be applied to approximate the associated boundary value problems.

Public Engagements

I've set up and run a Mathematics Cafe since 2011 where students can go to get help with the mathematical topics of their engineering degree.  Intiail support was provided by HESTEM and has been supported by the College of Engineering since 2012. To find out more see

Engineering Mathematics Resources and Cafe

I'm also the leader of the Engineering Mathematics Subject Teaching panel where I coordinate the deliver of the engineering mathematics modules to our first undergrauate students. In recent years I've taken an active role in the implementation of e-learning and e-assesment of engineering mathematics to large cohorts of students.
