Professor Mohammed's research is directed towards the fundamental understanding of carrier dynamics in a variety of light-harvesting systems for solar cells and X-ray imaging, including semiconductor quantum dots, perovskites materials, polymers, metal organic frameworks and copper halides glasses with the aid of cutting-edge ultrafast laser spectroscopy and four-dimensional electron imaging. The current research activities of Dr. Mohammed are focused on the development of highly efficient solar cells materials, and X-ray imaging scintillators and detectors for high resolution and low dose X-ray medical diagnostic and security inspections.​
