In 2013 Dr. Siebert became Director for strategic projects and since 2016 CEO of the Technological Research Division at CEA (CEA Tech). CEA Tech is a recognised world leader in semi-conductor, digital and renewable energy technologies across several sectors (automotive, aero, space, defence, manufacturing industry, energy, building and bank applications). In addition, CEA Tech is active in approximately 220 european projects per year and, has R&D technology partnerships with 11 of the world top 50 largest companies, including key technologies delivery to the most demanding ones.
In his capacity of CEO of CEATech, Dr. Siebert is in charge of conducting CEA Innovation strategy, responsible for tech transfer, start-ups creation and partnerships with companies, with proven results.
