Dr Johnston is building a bench-to-bedside research program in Interventional Oncology, and achievements have included introducing the first CT guided robot to the UK and developing ‘Smart Biopsy’ as a Biomedical Research Centre objective, which concerns precision sampling of subtumoural regions, sometimes guided by functional imaging signature (e.g., MRI/PET) using image fusion. His principal focus is optimising both biopsy and ablation procedures using emerging technologies and techniques.
Dr Johnston is a specialist advisor to NICE for interventional procedures and sits on the independent advisory board of the NIHR Clinical Research Facility.
