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
advised by Prof. Peter Paule , at ΕρΓΑ advised by
Prof. Ioannis Emiris
and at Galatasaray University advised by Prof. Meral Tosun.

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.
