Professor and Head of School in the School of Civil and Environmental Engineering

Research interest

Level 1: I research the behaviour of structural systems (buildings and bridges) constructed of reinforced and prestressed concrete.

Level 2: I’m particularly interested in bringing new and advanced materials technologies to the engineering of structures. My interests are in the use of high and ultra-high performance concretes, fibre-reinforced concretes and geopolymer concretes and in use of carbon fibre technologies for strengthening and repair of structures and structural systems.

Level 3: I develop physical-mechanical models for use in advanced computational and numerical tools such as FEM and for their use in the study of behaviour of concrete structures that are subjected to extreme events such as overload, fire, impact and blast loading.

Interest in engineering

Why did you get into engineering?

I actually knew I wanted to be an engineer from a very young age. I had a family history; a father who was an engineer, an uncle who was an engineer, and they were positive role models. I was always interested in mathematics and sciences and the built environment; so civil engineering and the delivery of infrastructure always interested me.

What are your research goals?

At the moment I’m looking at modelling for climate change: the behaviour of structures under extreme load states, whether fire, earthquake, or significant wind (e.g. hurricane loading events) that’s where our challenges lie. I’m also focussed on optimisation and design, using materials as efficiently as possible to develop efficient and safe structures.

What do people not understand about you do?

People often don’t understand the link between the role of science in identifying the problem and engineering in delivery of the solution to the problem.

Advice for prospective civil engineers

If you like achieving results for society; delivery of safe water supply, transport and/or structural systems, of dealing with the big issues of sustainability and the development and advancement of society through the solving of problems, then civil engineering is for you.
