My name is Iordan

I am an R&D Engineer at Gamestream in Nancy, France. I am also at the end of my Ph.D. studies in Computational Geometry, which I did as part of the research team GAMBLE. I worked with Monique Teillaud on the subject Delaunay triangulations of a family of symmetric hyperbolic surfaces in practice. The algorithm we propose is implemented in C++ and is open source, inspired by and based on CGAL. I participated in the ASTONISHING associate team and in the SoS ANR project.

I hold a Master's degree in Applied and Computational Mathematics from the University of Crete, Greece, as well as a Bachelor's degree in Applied Mathematics from the same institution.

About me
-- have a look at my cv --
My full name is Iordan Marinov Iordanov (Йордан Маринов Йорданов in Cyrillic). I was born in Stara Zagora, Bulgaria (that's here) on 20 September 1986, so I am years old. I grew up in a small village called Yulievo (here).

In 2000 I moved to Greece, to the beautiful island of Crete. I went to high school in Chania, and in 2005 I entered the Applied Mathematics Department of the University of Crete in Heraklion. I was surprised to know that I had the highest entry degree that year.

Due to personal reasons, I interrupted my studies in 2007 and headed to Italy, where I worked for a couple of years at Erbamea. I was warehouse manager and responsible for quality testing, and I had the chance to work with some amazing people in a truly unique environment.

However, I chose to continue with my studies, and in 2009 I moved back to Greece to pick up where I left off. In parallel, I found a job at the software company Nanosoft, where I focused mainly on developing client-server applications for Windows and Windows CE devices. This collaboration ultimately awoke my curiosity for Android applications. In 2013, I finished my undergraduate studies at the University of Crete.

With my degree in hand, I went back to Italy, and I found a job as software developer at the company 01S. My task was to get familiar with relational programming using the IDE Instant Developer, and implement a system to handle cadastral data acquired from multiple sources. Once I was more confident with Instant Developer, I was tasked with re-implementing the national-level calculations engine for the Italian 730 tax declaration form. My stay at 01S was very fulfilling, but I realized that I still wanted to learn more.

My aim was obtaining a Master's degree, for which I decided to head back to Greece. I enrolled into the Applied and Computational Mathematics program, and I was also fortunate and persistent enough to get a position at IACM-FORTH. At IACM, I had the fortune of working on an extremely interesting project with a very talented and passionate postdoctoral researcher, and our collaboration led to my very first scientific publication. I obtained my Master's degree at the end of 2015, concluding with a thesis for which I am very thankful to my professor, Menelaos Karavelas.

At the beginning of 2016, I moved to Nancy, France, and I started working on my Ph.D. thesis under the guidance of Monique Teillaud. Since then my perception on many things has changed quite fundamentally, and in three years I have traveled more than ever before. I will defend my Ph.D. thesis in March 2019.

Since January 2019, I am a Research and Development Engineer at the Nancy division of Gamestream.
