Julia’s early research on fatigue, linking microstructural characteristics, deformation mode, and crack length, forms the basis of microstructural design for fatigue resistant alloys for aeroengines, contributing to the development of safer and more efficient aircraft.

Julia’s current technical contributions lie in developing evidence-based policy to address climate change. The King Review of Low Carbon Cars, in 2008, led to developments ranging from new Vehicle Excise Duty bands for higher emissions vehicles, to Government support the development of the electric vehicle market in the UK. She leads on decarbonising transport for the Committee on Climate Change, and has recently been appointed to chair the Adaptation Sub-Committee, assessing the UK’s response to the risks of a changing climate. As a non-executive director of the Green Investment Bank she has overseen the development of an innovative set of Green Investment Criteria, used for assessing investments, company performance and remuneration.

Her other passion is developing the next generation of engineers and scientists, in a much more inclusive way, through relevant and exciting learning, supported by inspiring teachers.
