Associate Professor in Engineering Mathematics

Summary

Welcome! I am a Senior Lecturer (Associate Professor) in Engineering Mathematics at the University of Sheffield and part of the Dynamics group.

My team and I turn measurements into insight. We are experts in acoustics, elastic waves, and solid mechanics, and in the inverse problems that link sensor data to the quantities of interest such as stresses, material properties, and defects. We develop fast, robust methods that recover these quantities and quantify how much to trust the result.

We work closely with industry to design and de-risk new sensing and measurement methods, and we are always keen to hear about new challenging prediction and measurement problems. For an overview see my projects, publications or CV.

Projects

Software & Packages

Software for stress fields, wave propagation, and scattering.
