I am the Dean of Engineering at LSBU and was previously the Head of the School of Engineering at Portsmouth University. Prior to these appoints, I was a principle investigator in materials engineering at Queen Mary University of London and developed a range of techniques in nano mechanics at Weizmann Institute of Science in Israel.

I have published extensively and secured over £5M in research funding from government grants as well as direct support from industry.

My interests are in materials engineering and particularly the mechanical behaviour of composite-like structures. Many of my research activities have focussed on constituents with reduced dimensions, such as polymeric nanofibres, carbon nanotubes and graphene, and the building blocks used to assemble biological structures. Such research has often required the development of novel mechanical and imaging techniques. These interests have a broad range of applications from tissue engineering and healthcare to lightweight materials used in transport. Recent work examines engineering approaches to reproduce structures found in biological, particularly the diversity of teeth ranging from those found in humans to limpets, which I identified as the strongest biological material known. The engineering approaches I use are broad and cover advanced additive manufacturing (3D printing) as well as bioengineering approaches using synthetic biology.
