About Me

I am a power electronics engineer and research engineer. I studied at ETH Zurich, Switzerland (Bachelor, Master, and Ph.D) with a focus on power electronics, medium-voltage systems, and numerical analysis. My research interests include high-frequency magnetic components, medium-voltage engineering, high-frequency power magnetic materials, and advanced modeling techniques.

With my engineering and research activities, I am developing several open-source software and libraries for electrical engineering and numerical analysis (Python and MATLAB).

PyPEEC - 3D Quasi-Magnetostatic Solver

PyPEEC is a 3D quasi-magnetostatic PEEC solver developed at Dartmouth College within the Power Management Integration Center (PMIC). PyPEEC is a fast solver (FFT and GPU accelerated) that can simulate a large variety of magnetic components (inductors, transformers, chokes, IPT coils, busbars, etc.). The tool contains a mesher (STL, PNG, and GERBER formats), a solver (static and frequency domain), and advanced plotting capabilities. The code is written in Python and is fully open source!
