Hi, my name is Zafeirakis Zafeirakopoulos and I am an assistant professor at the Institute of Information Technologies of Gebze Technical University. I am a mathematician spending most of my time designing or implementing algorithms.

I hold a Ptychion (4-year degree) in Mathematics and an MSc. in Computational Science from the University of Athens. I was awarded a PhD from the Johannes Kepler University in Linz, under the supervision of Prof. Paule in the Research Institute for Symbolic Computation (RISC). After that, I held post-doctoral positions at RISC, ΕρΓΑ and Galatasaray University.
My CV is available here.


  • Symbolic Computation
  • Fast algorithms
  • Benchmarks
  • Linear Diophantine Systems
  • Polyhedral Geometry
  • Algebraic Combinatorics


  • Looking for master's and PhD students interested to work in my TUBITAK funded projects.
  • Looking for master's students interested to work in Symbolic Computation and related areas.
    • Application announcement for the master's program.
    • Contact me before the interviews.
  • Looking for students interested in working with Polytope Volumes in the frame of a BAP project.
