Aistis graduated from PhD at University of Warwick in 2015. Prior to joining XJTLU in September 2019, he worked as a Teaching Fellow of Mathematics and Statistics at London School of Economics (2016-2019) and as a Lecturer of Mathematics at Nottingham Trent University (2016). His research interests lie in Graph Theory and Combinatorics.
