About me

From Sfax to Chemnitz

Born in Tunisia, I graduated first in my class in electrical engineering and completed a master's in embedded systems ranked first in my cohort before moving to Chemnitz in 2017. I finished my doctorate summa cum laude in 2024, and today I lead the Impedance Spectroscopy group at the Chair of Measurement and Sensor Technology (Prof. Dr. Olfa Kanoun), TU Chemnitz.
