François Mazen is the Director for the Scientific Visualization team at Kitware Europe.

Throughout his career, François has focused on developing software solutions for scientific communities from research to industry. This topic includes numerical simulation methods, performance, Artificial Intelligence and large software architectures.

In 2008, François received his engineering degree at IFMA (French Institute for Advanced Mechanics) in Clermont-Ferrand where he was nominated for TOP 10 students.
The same year, he also received a Master of Science at Université Blaise Pascal (Clermont-Ferrand) where he specialized in Rigid Body.

Before joining Kitware, his previous 13 years of experience included 4 years at Ansys as a Software Developer to customize the Ansys Workbench application for specific customer requirements. He also worked for more than 6 years at Siemens PLM as Project Leader and Software Architect, where he integrated Robot’s Path Planning Technology in large applications like Siemens NX, Dassault Catia and Tecnomatix Process Simulate.

François is an open source enthusiast as he has been contributing to several open source softwares since 2007. Currently, he is an active member of the Debian Operating System development team.

Since 2021 he has led Kitware’s European Scientific Visualization team, including team management, strategy, technical expertise, operational excellence and business development.
