Biography:

Following her MPhys at the University of Oxford, Claire went to Switzerland to carry out her PhD studies at the Paul Scherrer Institute and ETH Zurich. She was awarded her PhD in 2017 for her work on 3D systems, which was recognised by a number of prizes including the APS Richard Greene Dissertation Award, the The Werner Meyer-Ilse Memorial Award, the ETH Medal, and the SPS Award for Computational Physics. After a postdoc at the ETH Zurich, she moved to the University of Cambridge and the Cavendish as a Leverhulme Early Career Research Fellow in January 2019, where she is focusing on the dynamics of three-dimensional magnetic nanostructures.

Research Interests

I am interested in the experimental investigation of three-dimensional magnetic systems, both extended systems - where the role of topology and complex interactions lead to fascinating 3D spin textures and behaviours - and patterned 3D magnetic nanostructures, where, via their geometry and the introduction of curvature, we can alter the magnetic properties, with implications for future devices.

To study these systems, we make use of sophisticated synchorotron X-rays to determine the three-dimensional magnetic configurations, and their dynamic behaviour, at the nanoscale.
