Professional background

Mr Hani Marcus is a consultant neurosurgeon at the National Hospital for Neurology and Neurosurgery and Honorary Associate Professor at the UCL Queen Square Institute of Neurology.

He specialises in treating patients with pituitary adenoma, and related skull base tumours. His expertise lies in the use of “keyhole” endoscopic approaches, completing fellowships in Calgary, Zurich, and London before his appointment. In 2020, he cofounded the British Neuroendoscopy Society to drive the advancement of endoscopic techniques and led the largest prospective study of patients undergoing pituitary surgery worldwide, including 866 patients across 30 centres in the United Kingdom and Ireland. He has also authored international guidelines on pituitary surgery through the Pituitary Society, where he serves on the education committee.

Mr Marcus has a research interest in technologies such as augmented reality, robotics, and artificial intelligence, for which he was awarded a PhD from Imperial College London. His work has attracted over £2.5 million in research funding, resulted in over 150 peer-reviewed publications, and frequently featured in the national and international press. He has been awarded numerous prizes and honours, including the Young Neurosurgeon Award by the World Federation of Neurosurgical Societies and the prestigious Hunterian Professorship by the Royal College of surgeons of England. He serves as Deputy Director of the Wellcome / EPSRC Centre for Interventional and Surgical Sciences (WEISS) and the regional Lead for Neurosurgery and Brain Cancer at the National Institute for Health Research Clinical Research Network.

Mr Marcus has a longstanding commitment to education, particularly in simulation-based learning. He earned a Postgraduate Diploma with distinction from Imperial College London, has published widely on educational theory, and is a Fellow of the Higher Education Academy. He cofounded the Queen Square Simulation Centre, securing significant funding and overseeing multiple courses. Importantly, he serves as the Programme Director for the UK's first Neurosurgery MRes program, emphasising face-to-face simulation-based learning.
