Mechanical Engineer at TRACTEBEL

Brussels Metropolitan Area

About

I have over 8 years of experience as a Mechanical Engineer in the nuclear energy sector. I started my career in the aerospace industry and in aerospace research. My experience is in mechanical equipment testing, qualification, supply and design, and technical coordination. Projects I worked on were mechanical equipment qualification by test for ITER in the South of France, with 6 types of mechanical equipment successfully qualified. More recently I lead a team of 19 young graduate engineers to deliver 75 mechanical ageing analysis documents for the 10 year lifetime extension of the Doel 4 nuclear powerplant. My working experience started at Sonaca in the field of materials and processes. The main activity consisted in defining and evaluating composite material processes and qualification testing. My Master's degrees were obtained in Electro-Mechanical engineering and Aeronautics at the VUB and at the von Karman Institute for Fluid Dynamics. I am results-oriented and can handle complex and challenging assignments effectively and possess the maturity and responsibility needed to lead a team and work as part of a team or independently. French and Dutch are my native tongues, my English is fluent and I speak fairly good Portuguese.
