Educational Background

  • MASc in Mechanincal and Mechatronics Engineering (Nanotechnology), University of Waterloo
  • BSc of Nanotechnology Engineering, Zewail City, Giza, Egypt

Research Interests

Topics: My research interests are 2D materials, optoelectronic devices, nanomaterials synthesis and characterization, thin films, chemical sensing.

Why 2D materials: 2D Materials are well-suited for many applications, thanks to their novel and exceptional properties and tunability. Applying them in LEDs and aiming to commercialize those devices is the reason why I’m interested in the program.
