Professor Andreas Zafeiridis received his Ph.D. from Temple University (USA) in exercise physiology. During his doctoral/postdoctoral studies, he worked in the Cardiovascular Research Laboratory (Temple University, USA), the Rehabilitation Department of Lung Diseases (Temple University Hospital, USA), and the Research Department of Cooper University Hospital (USA). During his stay in the USA, he studied the structural changes of cardiomyocytes in healthy heart failure patients and in experimental models of atrophy and hypertrophy of the myocardium (Temple University) and conducted numerous studies of basic and clinical research (Cooper Hospital). Since 2007, he has been a faculty member in the Department of Physical Education and Sport Sciences at Serres (Aristotle University, Greece). Currently, he collaborates with the Department of Medicine of Aristotle University (Papageorgiou Papanikolaou, and Ippokratio Hospitals) and participates in the pulmonary rehabilitation program. His research interests include the following: (i) exercise testing and prescription for the promotion of health and improvement of exercise performance, (ii) cardiovascular/autonomic/metabolic responses during aerobic/resistance exercise, and (iii) muscle/brain oxygenation and vascular function in healthy and diseased. He has published >95 international articles in exercise physiology and his work has been internationally recognized (Google Scholar/Scopus: h-index 34/29, citations 4430/22521).
