Biosketch
Sotiris Plainis completed his undergraduate studies in Optics and Optometry in Greece and UK. These were followed by postgraduate (MSc, 1995; PhD, 1999) and postdoctoral (1999-2001) research at the Department of Optometry & Vision Sciences, UMIST, UK. Since then he has been employed as Principal Research Fellow at the Laboratory of Optics and Vision (LOV), School of Medicine, University of Crete, being a faculty member of two postgraduate courses and having an active research group in visual optics, psychophysics and electrophysiology. Since 2012 he has been developing an eye movement-based method for the evaluation of visuo-motor and cognitive factors subserving reading performance.
He is appointed as a Visiting Research Fellow at Aston University (since 2018) and had served as an Honorary Lecturer at the University of Manchester (2006-2013). He is a module leader of the MSc course in "Optometry & Vision Science” (Università degli Studi di Milano-Bicocca). He is a fellow of the British Contact Lens Association (BCLA) and a member of the International Society for Contact Lens Research (ISCLR) and the International Association of Contact Lens Educators (IACLE) . He is an Advisory Board member of Zeiss Myopia Management committee. He is a past faculty member of the Basic Optics course organised by the European Society of Cataract and Refractive Surgery (ESCRS) and of the Education Committee of the European Academy of Optometry and Optics (EAOO). He also formed an International Vision Impairment (VI) Classifier, IPC. He has published widely in his field, edited a book (“Presbyopia: origins, effects and treatment”, SLACK Incorporated) and is a reviewer of Postgraduate Scholarships of the British College of Optometry.
