Born in Italy in 1951 and graduated in 1976, he spent a one-year neurosurgical residency in Hartford (USA) under the direction of Prof. Scoville, and from 1978 he began to work in Verona under the guide of Prof. Da Pian, a pioneer in vascular neurosurgery. In the early eighties he actively participated to the International Study on Timing of Aneurysm Surgery, directed by Prof. Kassell, and he spent some time with Prof. Drake in London (Canada). In the same period he began to cooperate with the Neuroradiology Service of Verona for the development of endovascular techniques in treatment of cerebro-vascular malformations. From 1985 to 1989 he organized 5 Italian courses on cerebro-vascular pathology in Verona, together with Prof. Da Pian. From the mid eighties he dedicated to the study of hemodynamics of cerebral AVMs and subarachnoid hemorrhage, introducing transcranial Doppler and cerebral blood flow measurements. In 1988 he worked as a research associate with Prof. Kassell at the University of Virginia, evaluating the efficacy of calcium channel blockers and neuropeptides in an animal model of cerebral vasospasm. In the nineties he was involved in the organization of two international studies on Tirilazad Mesylate in subarachnoid haemorrhage. In June 1992 he organized the International Conference "New Trends in Management of Cerebro-Vascular Malformations" together with Prof. Da Pian. In 1993 – after a short stay at the Gamma Knife Center of Charlottesville (directed by Prof. Steiner) - he began to treat cerebral AVMs with stereotactic radiosurgery in Verona, in association with Prof. Gerosa. From January 1999 to date he has been Director of the Section of Vascular Neurosurgery in Verona. From 2005 to 2010 he was involved in the planning of 3 international studies (CONSCIOUS 1, 2 and 3) on the efficacy of an endothelin antagonist in subarachnoid haemorrhage. In the last years he organized various meetings and courses on cerebro-vascular surgery, and in 2014 he was Chairman of the “7th European-Japanese Stroke Surgery Conference”. From 2013 to date he acted as National Coordinator of the Vascular Section of the Italian Neurosurgical Society. He his a recognized expert in vascular neurosurgery, with invitations to many italian and international conferences. To date, he has performed more than 1200 operations for cerebral aneurysms and more than 400 operations for cerebral angiomas. He has also published 170 full-lenght papers, edited 3 books on vascular neurosurgery, and prepared various chapters for prestigious international publications.
