Professor Hani Marcus

Professor Hani Marcus is a leading consultant neurosurgeon in London specialising in pituitary and skull base disease, including non-functioning pituitary adenomas (NFPAs), Cushing’s disease and acromegaly, as well as prolactinomas, TSHomas, Rathke’s cleft cysts and craniopharyngiomas.

He offers minimally invasive endoscopic surgery for these conditions, including transsphenoidal surgery for pituitary tumours and endoscopic skull base surgery. He is based at the National Hospital for Neurology and Neurosurgery, Queen Square, where he sees patients privately through UCLH Private Healthcare.

Professor Marcus completed integrated academic training at the University of Cambridge, Imperial College London, and University College London, with fellowships in Calgary and Zurich. He is a high-volume specialist in minimally invasive endoscopic surgery for pituitary adenomas, Rathke’s cleft cysts, craniopharyngiomas, and related skull base tumours, representing over 95% of his elective surgical work. He is a trustee of the Pituitary Foundation, the largest UK patient organisation, and has held leadership roles within the Pituitary Society, including serving as an editor for Pituitary.

Through these roles he has helped shape international guidelines on pituitary disease, including incidentalomas, prolactinomas, Cushing’s disease, acromegaly, and aggressive pituitary tumours, and has led initiatives such as the first patient-reported outcome measure for pituitary surgery, the first core outcome set, and the first international priority-setting partnership. 

He also serves as a Professor of Neurosurgery at the UCL Queen Square Institute of Neurology. His research focuses on robotics and artificial intelligence, for which he was awarded a PhD from Imperial College London. His group has secured over £10 million in funding, published more than 250 papers, and featured widely in the press. This work has been recognised with awards including the Best Young Neurosurgeon Award from the World Federation of Neurosurgical Societies and the Hunterian Professorship from the Royal College of Surgeons of England, and has attracted visits from Her Royal Highness The Princess Royal and the Secretary of State. He previously served as Regional Lead for Neurosurgery at the NIHR Clinical Research Network and is Chief Medical Officer of Panda Surgical, the spin-out company he co-founded, which developed the world’s first dexterity-enhancing handheld robots for pituitary surgery. 

Professor Marcus has a longstanding commitment to education, particularly simulation-based learning. He earned a postgraduate diploma with distinction from Imperial College London, is widely published on educational theory, and is a fellow of the Higher Education Academy. He co-founded the Queen Square Simulation Centre and is programme director for the UK’s first MRes in Neurosurgery.
