Michael A. Bekos

Assistant Professor
Department of Mathematics
University of Ioannina

Welcome to my website! I am Michael Bekos and I am an assistant 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.

Theses and Projects

Feel free to contact me if you are interested in writing your thesis or doing a project course in an area related to my research interests. In general, specific topics are available on request, but some general ones, which are continuously available, are listed here:
  • Graph Drawing (have a look to this introductory lecture, that is part of this series by Philipp Kindermann, for a quick introduction)
  • Linear Layouts of Graphs (have a look to this video by James Grime on NumberPhile for a simple and cool introduction)
  • Solving Hard Combinatorial Problems with SAT solving (for an application to linear graph layouts have a look here)
  • Algorithmic Map Labeling, Cartography and Geometry (for an in-depth introduction have a look to this survey)

More about me

I was born on March 30th, 1981 in Athens, Greece. I am married to Fouli and we have three wonderful kids, Maria-Artemis, Thanos and Nicole. I love playing basketball, listening to music, hanging out with friends, travelling and Christmas! I am passionate about anything and everything that has to do with research, e.g., collaborating with colleagues, working and exchanging ideas with students on diferent research topics, participating in research meetings, etc. Below you can find a few photos of mine from different events that I have participated in (always surrounded by friends).
