I am a medical physicist with interests in X-ray physics, radiation protection and applications of VR in medicine. I did an MSc in Medical Physics at Leeds University in 2009 and an MPhys at The University of York in 2008. I obtained a PhD at the University of Sheffield in 2017 in medical physics and image processing. From 2016 onwards David has focused on applying VR technology to meet medical needs, including a virtual reality colonoscopy, 3D medical data visualisation and simulation and therapy for different eye conditions such as nystagmus. I currently hold two part-time positions: as a clinical scientist in Diagnostic Radiology at Sheffield Teaching Hospitals and as a BRET funded postdoctoral researcher at the University.

Research interests

There are many potential applications of VR in medicine and my position in the University permits freedom to explore any avenue that shows potential for translation into medical practice. My main interests are currently focused on three specific areas of work.

  1. VR X-ray Simulation for Education - The X-ray Simulation project aims to provide a teaching programme for x-ray physics aided by a suite of novel resources. The programme aims to address an absence of simulation training resources for a wide audience of practitioners involved in X-ray system operation, as identified by new legislation (IRMER 2018). The suite of complementary educational tools also includes interactive 3D PDF models, a 2D smartphone app allowing the user to explore the effects of x-ray exposure settings on image quality and an interactive virtual reality x-ray room incorporating x-ray physics, placing the student in an environment which mirrors a real x-ray system.
  2. 3D Medical Data Visualisation - This aims to produce a VR interface for viewing and interacting with medical data across a wide range of clinical disciplines. This area is being developed in collaboration with the 3D Lab in Sheffield Teaching Hospitals.
  3. Orthoptics and Ophthalmology - The potential applications of VR to orthoptics are numerous. Specific examples include simulation of nystagmus (a condition where the eyes move involuntarily) in VR and a VR treatment tool for double vision. The former has been packaged as a freely available app on Android Play and App Store.
