Kotsios Stelios

Professor, Department of Economics, UOA

Member of the Coordinating Committee of the Postgraduate Programme

Stelios Kotsios studied Mathematics at the University of Athens, from where he obtained his degree. He has completed postgraduate studies in Informatics, Business Research and a Ph.D. in Applied Mathematics and specifically in “Non-Linear Discrete Systems”.

He has worked as a researcher or teaching staff, in HEI of the interior and abroad and is a professor in the Department of Mathematics-Informatics of the Department of Economics of the UOA.

Mr. Kotsios deals with the study of nonlinear discrete systems, difference equations, computational algebra, economic dynamics and applied mathematics in general. It is mainly interested in dealing with problems through algorithmic methods of symbolic programming. He has published in international journals with judges, has presented papers at conferences and authored two textbooks.

Since June 2019 he is President of the Department of Economics of the UOA.
