Profile

For enquiries please contact - SMPH-West-Operational@sheffield.ac.uk

I am a UKRI Future Leaders Fellow (FLF) and MR Physicist. I obtained a degree in Physics from Durham University in 2012, and a PhD in magnetic resonance imaging physics from the University of Sheffield in 2016. In 2017, I moved to Hokkaido University to undertake a post-doctoral research fellowship funded by the Japan Society for the Promotion of Science (JSPS), followed by a European Respiratory Society (ERS) Marie Curie postdoctoral research fellowship at the Center for Pulmonary Imaging Research (CPIR) at Cincinnati Children’s Hospital.

I returned to the POLARIS group in Sheffield in 2021 to continue my ERS fellowship and was awarded an FLF in late 2022.

Research interests

My research interests broadly encompass the development and optimisation of MRI methods for lung and cardiac imaging in infants and children, and imaging of hyperpolarised media.

Current projects

Pulse sequence development for multi-nuclear (1H and 129Xe) structure-function MRI of the lungs & heart
Feasibility of 1H and 129Xe lung & cardiac imaging in infants with pre-term birth related lung disease
Optimisation of non-Cartesian and free-breathing MRI reconstruction
Open-source software development for MRI
