Research profile
Léo Friedrich is a part-time researcher in the Electromechanics and Power Electronics Group within the Department of Electrical Engineering at Eindhoven University of Technology (TU/e). His research focuses on the numerical modeling of low-frequency electromagnetic problems, in particular involving eddy currents and nonlinear phenomena, within the context of design and shape optimization of magnetic devices. Léo develops specific frequency-domain finite-element solvers in the framework of isogeometric analysis (IGA), which aims for fast and accurate computations of steady-state solutions of electromagnetic and thermal field distributions on computer-aided design (CAD) models of electrical machines.

My passion is the research and development of numerical tools that enable the design-through-analysis of future industrial systems.
Academic background
In 2013, he finished the intensive two-year curriculum «classes préparatoires» in Mathematics, Physics, and Engineering Sciences (MPSI/PSI) at Lycée Marcelin Berthelot, Saint-Maur-des-Fossés, France. During the summer of 2015, he visited NCTU, Hsinchu, Taiwan as an exchange student, where he researched transport modeling, electrical characterization, and cross-section shape optimization of Gate-All-Around MOSFET's Arrays. Later that year, he spent four months as an exchange student in NTNU, Trondheim, Norway, where he studied optics and functional materials. In 2016, he received his «diplôme d’ingénieur» which is equivalent to an M.Sc. degree in Engineering, specialized in Physics and Nanoscience, from the «Grande École» Phelma - Grenoble INP, Université Grenoble Alpes, Grenoble, France. As of 2016, Léo joined the Eindhoven University of Technology, where he conducted his Master’s Graduation project, researching and modeling piezoelectric and electromagnetic solutions for harvesting vibrational energy. In 2020, he obtained his Ph.D. degree (cum laude) from the Eindhoven University of Technology for his thesis entitled: Isogeometric analysis of nonlinear eddy current problems. After completing a one-year PostDoc in the same group, he joined ASML as a Mechatronics Design Engineer specialized in electromagnetic actuation and cross-talk. Since 2023, he works for the European Patent Office as a patent examiner in the field of electric machines.
