Current research interests

My main interest in research is the biomechanical characterization of soft tissue. It is a fascinating field since it couples experimental engineering and medical issues. In particular, I specialize on the development and application of novel techniques to investigate soft tissue mechanical properties. For instance, during my PhD I worked on a technique based on quantitative ultrasound to non-invasively measure the force applied to superficial tendons, as well as their elastic modulus. More recently, I worked with ultrasound elastography to non-invasively assess intervertebral disc properties.

Currently, I am applying nonlinear microscopy techniques to investigate needle injury to the intervertebral disc. I collaborate on this project with Prof C. Peter Winlove, Dr Jude Meakin and Dr Jessica Mansfield.
