Who am I?
I am a CNRS senior research scientist (DR2) working at LIP, ENS de Lyon, in the ROMA team. Previously, I was a post-doctoral researcher at the Parallel Algorithms Project, CERFACS, Toulouse, France. Before that, I was at the Department of Mathematics and Computer Science, Emory University (now it is Maths), Atlanta, GA, USA. I have received BSc (1997), MSc (1999), and PhD degrees (2005) from the Department of Computer Engineering, Bilkent University, Ankara, Turkey, and HDR (2019) from ENS de Lyon.

- Rob H. Bisseling and I have worked on the optimal solution for the problem of partitioning an 16x16 mesh in four exactly balanced parts (details here). We have both analytical and experimental results showing that the optimal value is 57 for the standard connectivity-1 metric. Recent paper at the Utrecht University looks at the optimal partitioning of the 16x16x16 3D mesh into 8-parts. The world record from that paper is 1283; is this optimal?
