Dr. Nicolas Fiétier

Dr. Nicolas Fiétier was a senior research associate (Oberassistent) with the MOSAIC Group from March 2011 until July 2012. He is a French citizen, born in 1962 in Besançon, France. After leaving the MOSAIC Group, Nicolas started his own company "ARTS Engineering" in Valais (Switzerland), providing numerical simulation consultancy to the aluminum industry.


Nicolas graduated with an Engineering Diploma from Ecole Centrale de Lyon in 1986 and obtained a Master's degree in Aeronautics and Astronautics from the University of Washington at Seattle in 1987.


He then joined CERN in Geneva as a research and development engineer in collaboration with the Cyclotron Laboratory of the Centre Antoine Lacassagne in Nice, dedicated to cancer therapy. He participated in various international projects and applications of particle accelerators, such as the LEP collider under the guidance of Pierre Strubin, the European Light Ion Medical Accelerator under the leadership of Dr. Pierre Mandrillon, and the Energy Amplifier under the direction of Prof. Carlo Rubbia until late 1998. Dr. Fiétier worked on various aspects, including the remote control of devices and the computer-aided design of RF cavities, magnets, and beam lines. He developped and programmed hybrid particle-mesh simulationis for beam dynamics, including space-charge effects, and supervised a team of several technicians and engineers.


In late 1998, Nicolas joined the Laboratory of Computational Engineering (LCE/LIN) at EPFL, where he obtained his Ph.D. degree in 2002. His thesis work was concerned with the challenging topic of simulating viscoelastic fluid flows with spectral finite elements and it was done under the supervision of Prof. Michel Deville. During his Ph.D., Nicolas Fiétier actively participated in the development of the parallel C++ simulation toolbox SPECULOOS.


After his Ph.D., Nicolas stayed in the same laboratory as a postdoctoral fellow. He worked in collaboration with the companies M-TD and Alcan on computationally modeling and optimizing the extrusion process of hot aluminum alloys in an industrial environment. Following his postdoctoral research, Nicolas worked as a numerical simulation consultant for the company M-TD, developing fast computational algorithms and implementing new simulation software. His work also included mesh generation and data visualization tools.


In early 2006, Nicolas founded and led a start-up company specialized in the simulation of industrial processes involving non-Newtonian fluids and complex materials. In parallel, he held a part-time senior scientist and lecturer position in the Laboratory of Computational Engineering (LCE/LIN) at EPFL. Since 2005, he has been teaching several courses at EPFL, including non-Newtonian fluid mechanics and finite elements for incompressible fluid flows. He also authored a textbook in non-Newtonian fluid mechanics and was involved in the development of finite and spectral element and lattice Boltzmann methods to simulate viscoelastic fluid flows. Nicolas Fiétier supervised several Bachelor, Master, and Ph.D students and successfully wrote and managed grant applications. During three years, he also led the SMARTFISH project, dedicated to the design, manufacturing, assembly, and testing of a small remote-controlled airplane.


During his time in the MOSAIC Group, Nicolas focused on the development of adaptive multi-resolution particle methods and the further development of the PPM library. His applications included several problems in biomembrane dynamics, as well as computational bio-electro-magnetism.
