Abdelgahni earned his PhD in Physics from the University of Strasbourg (France) in 2007. He worked in the group of Dr. Jean-Yves Bigot – a pioneer group in femtomagnetism- at the Institute of Physics and Chemistry of Materials of Strasbourg (IPCMS). He developed a time resolved magneto-optical microscope to study the spin dynamics of magnetic nanostructures excited with femtosecond laser pulses and demonstrated for the first time the ultrafast gyroscopic magnetization dynamics that precedes the thermal fluctuations in superparamgnetic nanoparticles (size < 5 nm).
