Dr. Dimitrios Christaras
Dimitrios Christaras studied Applied Mathematics and Physical Sciences at the Technical University of Athens (NTUA). He continued his studies in France, where he received an MSc in particle physics from universities Pierre et Marie Curie (VI), Paris Diderot (VII) και Paris Sud (XI).
From 2009-2011 he worked as a young researcher at the University of Cyprus in the field of computational particle physics and more specifically on the study of the properties of elementary particles through lattice chromodynamics (LQCD). On the side, he also worked as a teaching assistant at the Department of Physics of the University of Cyprus.
He, then, moved to Pablo Artal’s Laboratorio de Optica in Murcia, Spain, where he completed his PhD in biomedical optics. His thesis was on light diffusion phenomena in vision and in imaging (http://hdl.handle.net/10803/396679).
From 2015 to 2017 he was a research associate at the UCL Institute of Ophthalmology in London, UK and he currently continues as an honorary research associate. His project was to design and build an adaptive optics system for psychophysical experiments in colour vision and high-resolution fundus imaging.
He eventually returned to Laboratorio de Optica in Murcia, where he worked as post-doctoral researcher (investigador doctor) on an innovative method and a corresponding optical instrument for the measurement of the optical density of macular pigment. His research resulted to patent and he was awarded the Visiometrics award for Best oral presentation at the VPOptics 2018 conference.
He has co-supervised 2 bachelor dissertations at King’s College London (KCL), one dissertation at the Universidad de Murcia and 3 student internships.
He has been a member of several societies such as the Optical Society of America (OSA), the Colour Group (GB), the Association for Research in Vision and Ophthalmology (ARVO) and he has been reviewing articles for scientific journals such as Journal of Optical Society of America A, Journal of Ophthalmology, Ophthalmic and Physiological Optics, Journal of Cataract and Refractive Surgery, Biosensors (MPDI).
In 2017 he was selected as the young research in focus from the European Vision Institute (http://www.vision-research.eu/index.php?id=1107).
