Dr Lees' research interests include:
- Prestressing tendons for concrete: The use of advanced durable materials as prestressing tendons for concrete would potentially avoid the current problems associated with the corrosion of steel reinforcement. Such materials of particular interest in offshore applications.
- Strengthening and repair of existing structures: With increased traffic loading, changes in design codes and the unexpected deterioration of structures, there is a tremendous need for ways of extending the lifetime of existing structures.
- Advanced analyses: Reinforced concrete structures are unusual in that they are often designed to be cracked under service loading. However, the presence of cracks introduces significant numerical challenges when modelling the behaviour of RC structures.
- Glass fibre reinforced polymer (GFRP) pipelines: Vast sums of money have been spent trying to mitigate the exposure of steel pipelines to corrosive environments, both internal and external. Pipelines made with FRPs will have longer predicted lifetimes and lower installation and maintenance costs.
- Sustainable concrete: Globally, 1.5 billion tonnes of cement are produced each year. As such, any environmental savings in terms of the energy consumption during the manufacture of concrete or the incorporation of waste materials into concrete will have a significant impact.

Janet Lees is a Reader in Civil Engineering in the Structures Group of the Department of Engineering at the University of Cambridge. She is also a Fellow of St John’s College. Her main research interests relate to the use of fibre reinforced polymers in construction and the strength assessment and enhancement of reinforced concrete.
Janet received her PhD in Structural Engineering from the University of Cambridge in 1997. Before embarking on a career in research, she spent three years in Industry working both for a Consultant and for a Contractor. She is a Chartered Engineer.
