After graduating from medical school at the Paris VI University in 1994, Stéphan Haulon started a general and vascular surgery residency at the Lille University Hospital. This was followed by a vascular surgery fellowship in 2000. In 2002 he defended his PhD-thesis in Biomaterial research and then left France to do a research endovascular fellowship at the Cleveland Clinic Foundation, under the supervision of Dr. Roy K. Greenberg. In 2003 he returned to Lille as a staff vascular surgeon at the University Hospital. In 2006 he was appointed Professor of Vascular Surgery. In 2009 he was invited to chair the vascular surgical department in Lille, and in 2017 was appointed chairman of the Aortic Centre at Hôpital Marie Lannelongue, Université Paris Sud.
Stéphan's main interest is in aortic surgery, particularly the endovascular treatment of complex thoraco-abdominal, arch aortic aneurysms and dissections, and intra-operative imaging applications. He has published extensively in the international peer review literature and is considered a key opinion leader on these subjects.
He is a co-director of the European Vascular Course, of the Critical Issues in Aortic Endografting Expert Symposium, of the CACVS meeting, and of the annual Charing Cross Symposium.
He was elected councilor at the board of the European Society for Vascular Surgery and at the board of the French Society for Vascular Surgery, and a SVS member. He is on the editorial board of the European Journal of Vascular and Endovascular Surgery, the Journal of Endovascular Therapy, and the Annals of Vascular Surgery.
