Stuarts research focuses on the development and clinical implementation of physics-based techniques for the treatment of cancer. These are mainly particle therapy, and boron neutron capture therapy, although Stuart also has interests ion other binary therapies and in conventional radiotherapy techniques. He has also been involved in work to use chemicals which can be analysed on the breath as markers of disease or treatment.
Laser induced particle beams and LIBRA
Stuart is a Co-Applicant and a work-package coordinator for the EPSRC basic technology grant looking at the use of high power lasers as potential sources of particles for radiotherapy. This LIBRA consortium involves a large number of UK Universities and research institutes (see the LIBRA project site for more details.) with the Birmingham contribution being mainly related to accurate dosimetry of the emerging proton beams.
Boron Neutron Capture Therapy
Stuart is also a lead member of the Birmingham project to develop boron neutron capture therapy as a viable clinical option for treatment of highly invasive tumours which are poorly treated by conventional methods. Work on this project is currently following three main themes:
• Development of the University Dynamitron accelerator as a clinical treatment facility, with all necessary associated dosimetry
• Fundamental studies on the radiobiology of high and low LET radiations and the interaction between the damage which they produce
• Understanding and optimisation of the delivery of the novel boron carrier compound, BPA-Mannitol, to patients with certain kinds of brain tumour
