Computational Electromagnetism
and Particle Simulations

I am a researcher working at on computational physics ranging from: electromagnetic wave propagation to plasma simulations. My work requires writing fast and accurate computer solvers that can fit measurements of real world devices.

computational electromagnetics, particle-in-cell, finite element method, automatic differentiation.

I.  Computational Electromagnetics

I am an Assistant Professor in the Faculty of Electrical Engineering of Warsaw University of Technology. My PhD thesis (2017) was dedicated to a Finite Element Method solver that helped designing a better transission line for EMC susceptibility test. A simple demonstration of a pule propagation in a shorted transmission line is presented in Fig. 1

II.  Plasma Simulations

Since then, I have focused on plasma simulations, using Particle-in-Cell (PIC) method. Our group develops a fast PIC code coupled with a Monte Carlo method for the modeling of collision processes in the plasma. An interactive simulation of classical problem of Two Stream Instability is presented in Fig. 2.

III.  Differential Programming

Ever since I started teaching it, I got fascinated with Differential Programming. In recent years, I have developed a few libraries for different types of automatic differentiation. Ultimately, such libraries might help build better Digital Twins of real world systems/devices.

IV.  Teaching and Supervision

I teach undergraduate and graduate courses in the broad area of programming languages and systems.

• DI3210 — Algorithms in Data Science (graduate, Spring).
• DI6240 — Data Security in IT Systems (undergraduate, Fall).

V.  Contact

Email is the most reliable way to reach me. Office hours are by appointment during the academic year.
