Angelos Kolias is a Clinical Senior Lecturer and Consultant Neurosurgeon in the Department of Clinical Neurosciences, Addenbrooke’s Hospital and University of Cambridge, Cambridge, UK. He also holds an adjunct Professorship at Humanitas University, Milan, Italy. In 2023, he was awarded a Hunterian Professorship by the Royal College of Surgeons of England.

He completed his neurosurgical residency in Cambridge and received subspecialty fellowship training in anterior skull base/pituitary neurosurgery at the National Hospital for Neurology and Neurosurgery, Queen Square, London.

His clinical interests include surgery for brain tumours (special interest in skull base/pituitary surgery), neuroendoscopy, spine surgery, neurotrauma, and general neurosurgery.

His research utilises a variety of study designs, including observational studies, dry laboratory experiments (bioengineering), and qualitative but the main emphasis is on the conduct of randomised trials. For his methodological work, he is collaborating with the IDEAL group (University of Oxford), COMET group (University of Liverpool), and the MRC Biostatistics Unit (University of Cambridge).

In the field of skull base/pituitary, he is working on i) the development of a core outcome set for pituitary surgery and ii) the implementation and evaluation of PET-guided surgery for pituitary adenomas. These are collaborative projects with Mr Richard Mannion (Clinical Lead for Neurosurgery/Skull base), Mr Tom Santarius (Lead for complex Neurosurgical Oncology), Prof Mark Gurnell (Lead for Endocrinology), and clinicians outside Cambridge.

In the field of neurotrauma, together with Prof Peter Hutchinson (Professor of Neurosurgery) and several UK and international collaborators, he has published impactful papers in journals such as the NEJM, Lancet, PLOS Medicine, Annals of Surgery, and JNNP. He is the Co-Chief Investigator of four NIHR-funded randomised trials and the Associate Director of the NIHR Global Health Research Group on Acquired Brain and Spine Injury.

During the COVID-19 pandemic, he is leading the neurosurgical theme of the CovidSurg portfolio of studies, which have resulted in several practice-changing outputs, published in journals such as the Lancet and Journal of Clinical Oncology.

He is also committed to advancing Global Neurosurgery and advocating for Young Neurosurgeons worldwide. He is an active member of the WFNS Global Neurosurgery committee. Under his leadership as the chair of the WFNS Young Neurosurgeons committee from 2019-2021, the committee made significant progress in defining and beginning to address the needs of Young Neurosurgeons globally. Finally, he was the inaugural chair and co-founder of the British Neurosurgical Trainee Research Collaborative, a research network of neurosurgical trainees in the UK that has delivered several, high-quality, multicentre studies.
