Dr. Ayman Al Haj Zen is an Assistant Professor in the College of Health and Life Sciences at Hamad Bin Khalifa University (Qatar). Dr. Ayman Al Haj Zen received his Ph.D. in 2006 from the University of Paris VII, where he studied the role of small proteoglycans in the regulation of vascular repair and atherosclerosis. Before joining the University of Oxford in 2010, he was a Postdoctoral Researcher at London Research Institute and the University of Bristol, investigating the role of cell-cell communication signaling in vascular development and regeneration. In Oxford, he was awarded an intermediate research fellowship from the British Heart Foundation (Oxford) Centre of Research Excellence in 2013 to establish his independent research program on therapeutic angiogenesis. Dr. Al Haj Zen’s research is focused on the identification of new therapeutic targets and strategies to promote functional neovascularisation and reverse the microvasculature instability in chronic vascular diseases.
