B. Sc. in Mathematics, Department of Mathematics, Aristotle University of Thessaloniki, Greece, 2004-2009.
M. Sc. in Mathematics, Department of Mathematics, Aristotle University of Thessaloniki, Greece, 2009-2011 (advisor: Prof. Dimitrios Betsakos). Ph.D. in Mathematics, Department of Mathematics, Universidad Autónoma de Madrid, Spain, 2012-2017, (advisor: Prof. Dragan Vukotić). Research
I'm interested in Complex Analysis and Geometric Function Theory, mostly in extremal problems for holomorphic or harmonic mappings, variational methods for univalent functions and, also, in some spaces of holomorphic functions.
I belong to the research project "Derivatives and integrability of univalent harmonic and analytic functions". (site of the project)
