Introduction
Erik is a Research Associate at Macquarie University currently working on algorithm development for inverse problems arising in wave scattering alongside Dr. Stuart Hawkins. His research interests include wave propagation, metamaterials, attenuation, constitutive modelling, PDEs, optimisation and machine learning.
He holds a PhD in Applied Mathematics supervised by Prof. William J. Parnell from the University of Manchester where he has strong connections with the MWM research group.

In this paper, we theoretically analyse wave propagation in two canonical problems of interest: fluid-filled thermo-visco-elastic slits and fluid-loaded thermo-visco-elastic plates. We show that these two configurations can be studied via the same pair of dispersion equations with the aid of the framework developed in García Neefjes et al. (2022),...
We present a unified framework for the study of wave propagation in homogeneous linear thermo-visco-elastic (TVE) continua, starting from conservation laws. In free-space such media admit two thermo-compressional modes and a shear mode. We provide asymptotic approximations to the corresponding wavenumbers which facilitate the understanding of dispe...

Recent work in the acoustic metamaterial literature has focused on the design of metasurfaces that are capable of absorbing sound almost perfectly in narrow frequency ranges by coupling resonant effects to visco-thermal damping within their microstructure. Understanding acoustic attenuation mechanisms in narrow, viscous-fluid-filled channels is of...
