Biography

I graduated from the University of Southampton with a first class honours degree in Physics in 1987 and went on to obtain a PhD in Medical Physics at the University of London (Royal Marsden Hospital) in 1990. After a brief spell in industry (working as a systems analyst for an oil company) I returned to academia, taking up a postdoctoral position and then a faculty position at the University of Utah (USA). In 1997 I returned to the UK, as a lecturer, senior lecturer then Professor at the University of Aberdeen. I was Director of the John Mallard Scottish PET Centre from 1997-2012 and have been programme coordiator for the MSc programmes in Medical Physics and Medical Imaging since 2016.

Research

Research Overview

My research has focussed on the tomographic radiotracer imaging techniques of Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) as well as Computed Tomography (CT) in general.

 

Current Research

Developing novel image reconstruction and image processing techniques for use in Nuclear Medicne.

Past Research

Developing PET methods to detect changes in brain function. This includes the use of Statistical Parametric Mapping and other statistical tools to detect changes in brain metabolism as measured with FDG-PET.

Measuring changes in cardiac metabolism with PET. This includes developing methods to measure glucose, oxidative and fatty acid metabolism.

Using medical CT scanners to study spontaneous imbibition in rocks. Applications include enhanced oil recovery.

Developing novel tomographic radiotracer imaging techniques to study fluid flow in porous and fractured rocks. Applications may include: enhanced oil recovery, carbon capture and storage and shale gas recovery. Current work uses Monte Carlo simulation techniques to compare PET and SPECT and to develop the optimum hardware and software for the task.
