Sophie is a Higher Research Scientist working on corrosion and stress corrosion cracking research for the power generation, nuclear and biomedical industries.
Sophie joined NPL in February 2018, having completed her PhD in Corrosion of Biomaterials at the University of Birmingham (UK). Her PhD was supervised by Prof Alison Davenport and Prof Owen Addison, and considered corrosion of Ti and its alloys used for biomedical implants. During her PhD she worked as a visiting scholar for 3 months in Centre for Electrochemical Science and Engineering, University of Virginia (USA) and for 10 months at the University of Alberta (Canada) for collaborative research. Previously, Sophie completed a BEng in Materials Science at the University of Birmingham, with her final year research project investigating microstructure and mechanical properties of cast aircraft components used for the Airbus A350.
Areas of interest
Sophie’s current research interests concern environmentally assisted cracking, including atmospheric stress corrosion cracking of stainless steel and high-strength low-alloy steel for nuclear and offshore applications. Her research also includes mechanistic studies on the transition from pitting to cracking, as well as the impact of environmental excursions on the crack propagation behaviour of steam turbine blade and disc steels for the power generation industry.
Sophie’s other interests include the corrosion of metallic alloys for biomedical applications. In this area she specialises in the corrosion and electrochemical metrology of alloys in simulated physiological solutions, including the role of protein- and inflammatory cell-induced metal dissolution behaviour.
