Mervyn Vergouwen obtained his PhD degree at the University of Amsterdam / Academic Medical Center in 2009. The title of his PhD was ‘Delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage – the role of coagulation and fibrinolysis’. From 2009-2010 he did a clinical/research stroke fellowship at the University of Toronto, Canada. After his return to the Netherlands, he worked as a postdoc at the Laboratory of Experimental Vascular Medicine at the Academic Medical Center to study the role of microthrombosis in the pathogenesis of delayed cerebral ischemia after subarachnoid hemorrhage in a mouse model. In 2011 he accepted a position as a staff neurologist at the UMC Utrecht and joined Prof. Gabriel Rinkel’s research group on aneurysmal subarachnoid hemorrhage.

His research focuses on unruptured intracranial aneurysms, diagnosis of (aneurysmal) subarachnoid hemorrhage, and brain injury after subarachnoid hemorrhage. This includes all processes that occur in the (sub)acute setting, including the initial hemorrhage and subsequent in-hospital complications (such as rebleeding, delayed cerebral ischemia, hydrocephalus, and infections), and the relationship of these processes with micro- and macrostructural brain injury, disability, and cognitive impairment.

His work was published in >100 publications and to date (December 2018) has been cited >3500 times.

Mervyn Vergouwen is the president-elect of the 15th International Conference on SubArachnoid Hemorrhage (ISAH) 2019 and co-PI of the Prospective Randomized Open-label Trial to Evaluate risk faCTor management in patients with Unruptured intracranial aneurysms (PROTECT-U).
