Mohammad Rahmani is an internationally renowned researcher, inventor, and academic specializing in the field of nanophotonics and metamaterials. His career is associated with prestigious Australian academic institutions, where he has conducted pioneering research. His work focuses on the development of optical metasurfaces, which are ultrathin, nanoscale structures designed to manipulate light with unprecedented precision. He is particularly known for introducing and developing the concept of "semantic metasurfaces," devices capable of encoding multiple distinct images or holograms onto a single surface, which can be selectively revealed by modifying properties of the incident light, such as its polarization. For his contributions, he has received numerous major awards, including the IUPAP Young Scientist Prize in Optics, the Warren Prize from the Royal Society of NSW, and a DECRA Fellowship from the Australian Research Council. He has also been elected a Fellow of Optica, and his work is regularly published in high-impact international scientific journals.
