Professor Alireza Z. Moshfegh received his PhD in Physics at University of Houston, Texas (USA) in 1990. After two years of Post-Doctoral research activity in Texas Center for Superconductivity, he joined as an assistant professor in Department of Physics at the Sharif University of Technology (SUT) in Tehran, Iran. He is the founder of Vacuum Society of Iran (VSI) and acted as its president (2004‒2010) as well as co-founder of Iranian Society of Surface Science &Technology (ISSST). He is selected as the first ranked physics researcher in Iran in 2011. He established a large multidisciplinary research group called NEST (Nano-Energy-Surface-Thin films) (Farideh Kolahdouzan, Nahal Goodarzi, Mahboobeh Setayeshmehr, Dorsa Sadat Mousavi, Alireza Z.
