Dr. Selim has a broad research program in the field of oxides and wide band gap materials. Her research covers a wide range of topics in semiconductors and dielectrics including synthesis, thin film technology, optoelectronics, transport properties, and defect studies. She is expert on positron annihilation and luminescence spectroscopies and has been very active in developing new techniques and building instrumentation for defect and luminescence measurements.
Selim has earned international recognition in a number of scientific communities that has been reflected in selecting her to be:
- One of the 13 members of the International Scientific Committee of Positron and Positronium Chemistry since November 2014.
- Secretary of the International Academic Advisory Committee on “Persistent and Photostimulable Phosphors” since May 2015.
- One of the 10 members of Positron Working Group at the Thomas Jefferson Laboratory (JLab).
Selim is editor of scientific book, author of 78 peer reviewed articles and two book chapters and sole inventor of 3 patents, 1 issued in 2016 and 2 pending, in addition to her significant invention at the beginning of her career “Accelerator based positron annihilation spectroscopy” technique which extends positron annihilation spectroscopy to numerous new fields in materials science. The technique is known today as Gamma induced positron spectroscopy (GIPS); it has been recently adopted to build a unique materials research facility at the superconducting accelerator facility in Dresden, Germany.
