Giannis Karagiannakis, Ph.D






I am adjunct lecturer in National & Kapodistrian University of Athens (NKUA), visiting professor in University of Malta and Post-doc researcher of the Psychological Sciences Research Institute of Catholic University of Leuven in Belgium. My Ph.D. work in the Faculty of Primary Education of NKUA focused in the detection of difficulties in Mathematics. I hold a M.Ed. in Didactics of Mathematics from the Mathematical Department of the NKUA, a Degree of Mathematics from the Aristotelian University of Thessaloniki as well as a scholarship on the Program of training professionals: "Differentiating Instruction and Team Teaching in Mathematics & Literacy" of Graduate School of Education of Harvard University. My research interest is in the field of Mathematical Learning Difficulties (MLD): exploring cognitive roots of MLD, and developing scientifically informed effective remedial interventions for students 8-18 years old. I have been publishing papers in international research journals with reviewers, I have been presenting my work in a number of events in Greece and abroad, and I have been an invited speaker in various international conferences. I have been participating as a partner in the following European research projects related to learning disabilities: EUSpLD (2014-2017), DYSSpeLD (2011-2013) and NSRF (2007-2013). I have multiannual experience in assessment, planning and application of individualized intervention programs for students with MLD as well as in delivering training and supervision programs for educators in Greece and abroad. I am scientific supervisor of Maths section of Eureka Leuven school in Belgium. Finally, I am CEO of the Hellenic Dyslexia Association and board director of the European Dyslexia Association (EDA).
