Michael A. Bekos

Associate Professor
Department of Mathematics
University of Ioannina

Welcome to my website! I am Michael Bekos and I am an Associate Professor at the Department of Mathematics of the University of Ioannina in Greece. I received my PhD from the National Technical University of Athens in 2009, and my MSc and BSc from the University of Ioannina in 2004 and 2002, respectively. I have also served as postdoctoral fellow at the algorithmic groups of the National Technical University of Athens and of the University of Tübingen.

My research interests focus on theoretical aspects of Computer Science and Discrete Mathematics; in particular, on the development of algorithms and combinatorics to solve problems mostly from the research areas of Graph Drawing, Graph Theory, Information Visualization and Map Labeling. My research work includes research papers published in prestigious journals and peer-reviewed conferences, which have received several citations.

More about me

I was born on March 30, 1981, in Athens, Greece. I am married to Fouli, and together we have three wonderful kids: Maria-Artemis, Thanos and Nicole. I enjoy playing basketball, listening to music, spending time with friends, travelling and Christmas! I'm deeply passionate about research in all its forms, e.g, collaborating with colleagues, exchanging ideas with students across different topics, and participating in research meetings. Below, you'll find a few photos of mine from various events I've participated in (always surrounded by friends).
