My main interests are spinal problems and brain tumours, including tumours of the skull base and pituitary gland. I work on all aspects of spinal disease including infection, tumours, trauma and degenerative / wear and tear conditions. In particular, i have an interest in back pain and the role of minimally invasive spinal surgery in treating people with spinal problems, having witnessed the advantages of keyhole techniques for my own patients. I have completed a fellowship in Brisbane, Australia where I became skilled in all aspects minimally invasive spinal techniques and along with Mr. Trivedi, we have built up a large minimally invasive spinal practice here in Cambridge.As a PhD in the field of chronic pain, having spent my research time in London and at Harvard University in Boston under Professor Clifford Woolf, a leading international pain specialist. I remain active in research and have published a large number of scientific papers on the subject of chronic pain, nerve pain, spinal disease and minimally invasive spinal techniques.
