Lecturer/Senior Lecturer

Research and teaching of computational applied mathematics. Dr Chappell teaches on the modules Numerical Methods for Ordinary Differential Equations and Mathematical Recipes. He conducts research in computational applied mathematics with applications in industry.

Career overview

In 2007 Dr Chappell completed his PhD at the University of Brighton on modelling transient acoustic fields radiated by vibrating elastic structures with application to modelling sound fields from loudspeakers.

He continued to work at the University of Brighton until 2009, conducting research in the numerical analysis and solution of the wave equation in unbounded domains and on numerical approaches for nearfield acoustic holography, a process whereby the acoustic intensity field may be studied on a structure from measurements of the exterior acoustic field.

In 2009 Dr Chappell moved to the University of Nottingham to work as a postdoc researching high frequency wave energy transport in built up systems. This work lead to a knowledge transfer secondment position with Jaguar Land Rover in January 2012 on modelling high frequency wave energy flow in large moulded aluminium car body components. In September 2012 he started work as a lecturer in numerical analysis at Nottingham Trent University.

Research areas

Dr Chappell's research interests surround Industrial mathematics, mathematical modelling and numerical analysis including:

  • Time-dependent wave propagation problems
  • Boundary integral and boundary element methods
  • Convolution quadrature methods
  • Inverse problems in acoustics, electromagnetics and applications in medical imaging
  • Fluid-structure interaction problems
  • High frequency wave modelling
  • Wave energy flow in complex industrial and engineering structures
