Dr. Atef Zekri graduated with a PhD in Physics in 2017 from the University of Oldenburg (Germany). He worked as a Post-Doctoral Research Fellow in the Energy and Semiconductor research group within the Institute of Physics in the University of Oldenburg (Germany). Atef is a charted scientist, and a member of the Institute of Physics. Atef obtained his Master of Science in Materials Science from Saarland University (Germany) and his Bachelor of Science from Saarland University (Germany) as well as a Bachelor of Engineering from EEIGM (École Européenne D'ingénieurs en Génie des Matériaux, France). His current research interests focus on state-of-the-art electron microscopy and advanced characterization techniques, including Scanning and Transmission Electron Microscopy (SEM/TEM), Atomic Force Microscopy (AFM), Energy-Dispersive X-ray Spectroscopy (EDS), and Focused Ion Beam (FIB). His work spans a wide range of materials and applications, with particular expertise in energy storage systems, corrosion studies, and microstructural analysis of semiconductors, thin films, and solar cell materials.
