Prof. Marc Levivier. MD, PhD, IFAANS, trained in Neurosurgery at the Free University of Brussels (ULB). His clinical and research activities focus on image-guided and mini-invasive neurosurgery, including stereotactic and functional neurosurgery, neuro-oncology, and non-invasive radiosurgery for which he has been a Gamma Knife user since 1999, at the University Erasme Hospital in Brussels.

In 2007, he was appointed as Full Professor at the University of Lausanne (UNIL) and Chairman of Neurosurgery at the Lausanne University Hospital (CHUV). He was also the co-director of the Lausanne-Geneva ‘Centre Universitaire Romand de Neurochirurgie’ and the Director of the Gamma Knife Center at CHUV, which opened in 2010.

In that context, his activities focused more specifically on radio-neurosurgery, with new technical developments, investigations aiming at a better understanding of the radiobiological effects of radiosurgery, and advances in the improvement of functional results for patients with complex skull-base tumors, using combined approaches with microsurgery and radiosurgery, as well as the development of new algorithms to optimize radiosurgery dosimetry planning in collaboration with the start-up company Intuitive Therapeutics.

His academic activities are at the basis of more than 400 scientific publications and numerous awards and grants. He has given more than 300 courses and conferences. He is a member of many international scientific societies and committees (AANS, CNS, EANS, …), and he was the 2022-2024 President of the International Stereotactic Radiosurgery Society (ISRS). He currently serves as chair of the Education Committee of ISRS.
He is a member of the Belgian Royal Academy of Medicine and an international member of the American Academy of Neurological Surgery.

In Februray 2025, he was appointed as Emeritus Professor at the University of Lausanne and he started a new clinical activity at Hôpital La Tour in Geneva, with a specific focus on Linac-based radiosurgery for patients with cranial and spinal conditions in the framework of the NeuroKnife Center.
He is the local organizer of the coming ISRS CNS Summit that will take place in Geneva, June 4th-5th, 2025 (isrs-cns-summit.org).
