Associate Professor in Engineering Mathematics

University of Sheffield

Intro

Welcome! I am an Senior Lecturer (Associate Professor) in Engineering Mathematics at the University of Sheffield and also part of the Dynamics group. I am an expert in acoustic, elastic waves, and more broadly solid mechanics. I mostly develop new sensing and measurement methods and enjoy working on industrial problems. For an overview see my projects, publications or CV.

Waves in Complex Materials

The aim is to understand how waves (like sound, radio, light, and vibrations) behave in materials with random microstructure.

Industrial Mathematics

Combining maths, data and code to solve commercial and industrial problems.

The mechanics of soft solids

How do we mathematically describe the stresses and deformation of anisotropic soft solids.
