Research Interests

My research interest is in techniques for solving equations from mathematical physics, motivated by sound wave propagation. My research is, for example, on the construction of reliable approximations to Wiener-Hopf equations and, more generally, Riemann-Hilbert equations. These approximations are readily computed offering physically accurate information about the solution in the cases where numerical methods give poor results. More generally I am interested in developing mathematically sound methods which are practically useful in acoustics and their numerical implementation. I have worked on aeroacoustic modelling of adaptations which allow owls to fly near silently with applications of noise reduction in airframes and wind turbines.
