Biography

Background

After graduating with a MSci in Natural Sciences, I remained at Cambridge University to obtain a PhD in the development of novel magnetic resonance (MR) pulse sequences. During this time I developed several techniques including the Thrippleton-Keeler filter for suppression of zero-quantum coherence artefacts. Following postdoctoral research in solid-state MR at the Massachusetts Institute of Technology and the University of Glasgow, I joined the University of Edinburgh in 2008 to work with Professor Hilary Critchley on a clinical trial of MR imaging of patients with uterine fibroids.

In my current role I support a large number of academic and commercial clinical studies requiring MR imaging. In 2016 I helped to establish the Edinburgh Imaging Facility at the Royal Infirmary of Edinburgh, where I continue to provide scientific input to facility operation. My research focus is presently advanced neuroimaging in cerebral small vessel disease and other conditions, including DCE-MRI and cerebrovascular reactivity measurement.
