Personal profile

Biography

After obtaining my Engineering degrees from Churchill College, Cambridge, I undertook a PhD in the structural optimisation of composite helicopter rotor blades at Bristol University. After defending my thesis, a Leverhulme Study Abroad Studentship enabled me to move to the University of Cape Town to investigate the resistance of hybrid composite panels to localised explosive blast loading, with an academic visit to Oxford University to conduct material characterisation tests.

I then spent some time in industry, working in oil and gas consultancy where I led a small team of junior engineers on R and D projects, and also in finite element analysis consultancy where I worked on a wide range of engineering problems for industrial clients.

I then returned to Cambridge University, to investigate the effect of waviness (and other) defects upon the compressive strength of fibre reinforced composite materials. At the end of that funding, I spent two years working as an expert witness in structural failures and in RTA reconstruction (with a particular emphasis on the protection offered by bicycle helmets) before taking a an academic position at Coventry University to teach structural analysis and finite element modelling.

Research Interests

Structural analysis and optimisation; Impact mechanics – and optimisation of protective structures (such as bicycle helmets).; Composite materials – particularly failure, fatigue, defect/damage tolerance and repair.

Vision Statement

I intend to pursue research in composite materials, with a particular interest in the micromechanics of failure, including damage tolerance and fatigue.

A correct understanding of the micromechanics of failure is essential to accurately predict the strength and service life of composite structural components. This in turn will allow less conservative, more highly optimised designs to be produced, enabling ever more challenging targets for weight reduction and lifecycle cost to be met.

I am currently seeking industrial and academic partners to collaborate in this interesting field.
