Alexandros G. Vanakaras, born in 1970, is Professor of computational/theoretical materials science of self assembly and self organization in soft mater at the department of Materials Science of University of Patras, Greece. He obtained his Ph.D. in Physics (thesis title: Specific Interactions and Molecular Organization in Liquid Crystals) in 1997, at university of Patras, under the academic supervision of Prof. D. J. Photinos. As PhD researcher he spent several months at the university of North Carolina, Dept. of Chemistry (E. T. Samulski‘s group), Univ. of North Carolina, Chapel Hill, (US). After his 18 months military service he worked as post doctoral researcher at the Department of Physical Chemistry (C. Zannoni’s group), University of Bologna (Italy).

He became lecturer at the department of Materials Science in 2002, Assistant Professor in 2006 and Associate Professor in 2012. He has given more than 20 plenary and invited talks at national and international meetings over the last 5 years, is author/co-author of over 40 publications.
