Meet the team (nuclear medicine physics)

Nuclear medicine physics is a small but effective team, comprised of seven permanent physicists (5.8 WTE), including four medical physics experts (MPEs). We work with multiple Scientific Training Programme (STP) trainees and also provide route 2 training.

  • Matt Guy
    Matt Guy (he/him)

    Head of imaging physics

    Matt is a consultant clinical scientist and medical physics expert (MPE). He leads the imaging physics group which includes MRI physics, nuclear medicine physics, scientific computing and neurological physics. Within nuclear medicine, Matt has extensive experience across both diagnostic and therapeutic applications of nuclear medicine, including PET/CT. Whilst working at the Royal Marsden and Institute of Cancer Research, Matt developed one of the first patient-specific 3D dose planning systems for molecular radiotherapy (MRT), and worked extensively on improving the quantification of high count-rate SPECT imaging as part of his PhD. Matt has contributed to a variety of national and international working parties, producing guidelines and strategies for MRT. His nuclear medicine research activities have focussed on enabling MRT dosimetry, including through the use of low dose and dual energy CT and correcting respiratory motion during imaging. He has also transferred this work to patient-specific drug development and targeting. Matt is a member of the UHS research leaders programme, focussing on digital diabetes technology development.
