His sub-speciality interests include pituitary, anterior skull base and complex spine surgery, utilising minimally invasive techniques. He is the lead consultant for Pituitary surgery in Manchester and introduced the endoscopic approach to the region. SRFT is a national and international Visitation centre for Minimally Invasive Surgery, with regular visits from surgeons wishing to learn such ‘key hole’ surgical techniques.

He has a strong interest in clinical and basic science research in Neuroscience, qualified to a doctorate level, with over 80 publications and international presentations.


Marcel Ivanov


Marcel Ivanov is a consultant neurosurgeon and honorary senior lecturer in Sheffield.  He is sub-specialty Lead for Spine. His spinal practice includes treatment of spinal trauma, infection and tumours, and all aspects of degenerative spinal disease including disc prolapse and spinal stenosis.

He developed an interest in:

- minimally invasive neurosurgical techniques in degenerative and trauma cases

- treatment of spinal cord tumors and vascular lesions

- neuronavigation of the spine and brain

- intraoperative imaging

He is active in education (member of EANS Training Committee and Oral Board Examination Committee; AOSPINE UK Council Officer). Mr Ivanov is helping with many spine-related courses and conferences both at national and international levels and has been a keynote speaker at a handful of international symposia.


Rodney Laing


Rodney Laing was appointed as a Consultant Neurosurgeon, with an interest in spinal neurosurgery, at Addenbrookes Hospital in 1995. Since then his practice has expanded to include both complex spinal neurosurgery and minimally invasive (keyhole) surgery, which can often be performed as a day case.  Rod specialises in the treatment of degenerative disease, trauma, tumours and syringomyelia.

In 2000 he was appointed director of higher neurosurgical training for the Eastern Deanery; in this capacity he was directly involved in neurosurgical training both at local level and at the Royal College of Surgeons in London.  In addition Rod has been secretary of the British Cervical Spine Society and worked to establish the British Association of Spine Surgeons where he served on the Executive until recently.  From 2009 -2012 Rod was Clinical Director of Neurosurgery; he oversaw many changes within the Neurosurgical centre and introduced key initiatives including day case spinal surgery. In 2012 Rod was elected to the Council of the Society of British Neurological Surgeons.  Rod was Clinical Director of Neurosciences from 2014 to 2017 and in 2015 was appointed to the United Kingdom Spine Societies Board.

One of the biggest challenges in spinal surgery is measuring outcome, which is often subjective. His team have undertaken a number of studies in this area, including the assessment of various outcome measures (Roland-Morris, SF-36) and how these outcome measures can be used to demonstrate the effectiveness of spinal surgery for a number of different spinal conditions such as Chiari malformations and syringomyelia, lumbar disc prolapse, cervical myelopathy and metastatic spinal disease.

He is pioneeering new surgical strategies in spinal surgery, with an emphasis on minimally invasive techniques that are helping to shorten hospital stay and improve recovery. By embracing minimally invasive techniques in the clinical service Cambridge has become one of the largest minimally invasive spinal centres in the UK and this has provided the opportunity to carry out further outcome based data and plan clinical trials comparing these techniques to traditional approaches.

In terms of clinical trials the team are currently preparing the participation of Cambridge as a leading UK centre in the RISCIS trial and are initiating a clinical phase 1/2 trial investigating transplantation of Olfactory Ensheathing Cells in Spinal Cord (OEC-SCI Trial). Rod has also worked with the department of population health sciences and the national institute for health research collaboration in Bristol and a trial of selective nerve root block in assessing patients with non-concordant symptoms and signs is being planned.


John Leach

John Leach is a Consultant Neurosurgeon in  Manchester. His sub-specialty Interests are Spine and Neuro-oncology. He was the Clinical Lead 2012-15 and the sub-specialty Lead for Spine. He completed his neurosurgical training in Oxford and Melbourne. His research interests are Saccadic eye movements,  Gliomas, Lumbar disc disease, Intramedullary spine tumours

Erlick Pereira


Mr Pereira is Reader in Neurosurgery at St George's, University of London and Affiliated Professor at the University of Porto.  His clinical subspecialties are functional and complex spinal surgery.  His main research interests are movement disorders, pain, spinal injury, deep brain stimulation, neuromodulation, radiofrequency lesioning and neural interfaces. 

Mario Teo


Mario Teo is a Consultant Neurosurgeon and Honorary Senior Clinical Lecturer at Bristol Institute of Clinical Neuroscience, North Bristol University Hospital, having completed a Cerebrovascular and Skull Base fellowship at Stanford University, California, USA. He has a special interest in minimally invasive neurosurgery (cranial and spine), management of skull base tumours and vascular pathologies including endoscopic endonasal approaches and cerebral revascularizations.


His research focus includes moyamoya disease, cerebral aneurysm, arteriovenous malformation, cavernoma, schwannoma, meningioma, skull base tumours and neurocutaneous disorders. He authored numerous peer-reviewed publications, editorials, book chapters, and is also an advocate of collaborative clinical and scientific research, at local, national and international level.

Rikin Trivedi


Rikin Trivedi has specialist interests in spinal, cerebrovascular and skull base surgery having received sub-speciality fellowship training in these areas in the USA. Whilst on fellowship, he gained proficiency in minimally invasive (keyhole) surgery techniques and performed the first keyhole lumbar discectomy in the region, shortly after his return. His spinal practice includes treatment of spinal trauma, infection and tumours, and all aspects of degenerative spinal disease including disc prolapse and spinal stenosis. 80% of spinal practice is now performed using minimally invasive (keyhole) techniques including day case lumbar discectomy and decompressions.

His research interests to date have been in developing novel imaging techniques for assessment of vascular disease and have evolved to evaluate novel strategies in the treatment of spinal disorders. He has supervised numerous research student projects and currently co-supervise a PhD student thesis. He has trained fellows in both cerebrovascular and spine surgery, and is currently Co-Director of the Cambridge Spine Fellowship.


Kevin Tsang


Kevin Tsang graduated from Guy’s and St Thomas’ Hospitals and undertook specialty training in Plymouth and Bristol.
