The Institute for Infrastructure and Environment is among the leading centres of civil and environmental engineering research in the UK. The Institute seeks new technologies to solve real-world problems in order to promote sustainability. Key research areas include: behaviour and design of structures in fire and other extreme events; fire science and fire safety engineering; shells and containment structures; nonlinear finite element modelling of complex structures and structural collapses; mechanics and transport of granular materials and multiphase media; computational mechanics and bio-mechanics; fibre-reinforced polymer composites in structural strengthening and repair; high-speed rail; intelligent infrastructure and non-destructive evaluation; sustainable water and wastewater treatment technologies; water supply; waste management and resource recovery.
