Co-CEO

Before launching Hexaly, Thierry headed the Operations Research (OR) team at Bouygues, one of the biggest French public corporations. Graduated from École Polytechnique (X95), he holds a Ph.D. in computer science from Avignon University (2004) and a Habilitation from Nantes University (2014).

He has published papers in top OR journals. Several awards distinguished his research: 2005 Doctoral Prize for Innovative Applications by the French Computing Society, 2006 Robert Faure 3rd Prize by the French Operations Research Society (ROADEF), and finalist of the 2012 EURO Excellence in Practice Award.

Fred, Ph.D.

Co-CEO

Fred holds a Ph.D. in computer science from Aix-Marseille University (2005) and a Habilitation from Sorbonne University (2013). He won several international OR competitions: 1st Prize of ROADEF 2005 Challenge, 2nd Prize of ROADEF 2007 Challenge, ROADEF 2011 1st Prize for Industrial Applications.

He has published twenty papers in international journals and conferences at the interface of discrete mathematics, computer science, and operations research. In 2012, he was the recipient of the ROADEF Robert Faure 1st Prize and finalist of the 2012 EURO Excellence in Practice Award. He served as president of ROADEF from 2014 to 2015.

Julien, Ph.D.

Head of Science

Julien obtained a Ph.D. in computer science from Grenoble University (2011). His research was at the intersection of mathematical optimization and machine learning. He was awarded in several international OR competitions: 2nd Junior Prize of ROADEF 2009 Challenge, 3rd Senior Prize of ROADEF 2010 Challenge, Kaggle Santa’s Stolen Sleigh 2015 Challenge.
