Dr. Elmahdy studied physics at Mansoura University in Egypt. After finishing his Ph.D. at Ioannina University in Greece, he went back to Mansoura University as a Lecturer of experimental physics. From 2008 until 2013, he joined Prof. Friedrich Kremer’s research group at the Faculty of Physics and Earth Science at Leipzig University in Germany as a postdoctoral researcher. During this period, he has conducted research, teaching, and organizational duties. After finishing his first postdoctoral at Leipzig University, he joined Prof. Manfred Stamm’s research group at Leibniz Institute for Polymer Research (IPF) Dresden. After finishing the second postdoctoral at IPF, Dr. Elmahdy went back to Mansoura University as an Associate Professor of experimental physics at the Physics Department, Mansoura University. In January 2021, Dr. Elmahdy has promoted to Professor of Material Science at Physics Department, Mansoura University, Egypt. Currently, he is working as Associate Professor of Material Science at Physics Department, College of Science &Humanity Studies, Prince Sattam Bin Abdulaziz University, Alkharj, Kingdom of Saudi Arabia.
