Research interests

The overarching aim of Dr Lees' research group is to provide more sustainable infrastructure solutions. This is achieved through an improved understanding of existing infrastructure assets, the use of new materials and the creation of advanced structural systems. We have particular interests in concrete and FRPs (Fibre Reinforced Polymers) and investigating novel ways to combine these materials for further advantage.  

Strategic themes

Energy, transport and urban infrastructure

Lifetime extension of reinforced concrete structures; strengthening and repair of existing structures; advanced materials for new construction.

Manufacturing, design and materials

Tailored reinforced concrete infrastructure; cement efficiency as a route for CO2 mitigation.

Research projects

  • Bridge Engineering
  • Structural Theory
  • New Materials in Structural Engineering

Teaching activity

  • First year Structural Design Course


Dr Janet Lees is a Professor of Civil Engineering at the University of Cambridge and is a Fellow of the Institution of Civil Engineers.  She is the Head of the Structures Research Group at Cambridge and a Director of the University of Cambridge EPSRC Centre for Doctoral Training in Future Infrastructure and Built Environment. She is a Fellow of St John's College.

Before embarking on a career in research, Dr Lees spent time in Industry working both for a Consultant and for a Contractor.  She received her PhD in Structural Engineering from the University of Cambridge.  She leads the Concrete Infrastructure Research Group (CIRG) where the main research interests of her group relate to reinforced concrete and the use of advanced materials in construction.  Ongoing project areas include the strength assessment of existing reinforced concrete infrastructure, fibre reinforced polymer (FRP)/concrete systems and sustainable concrete infrastructure.
