I am Ramin Yousefi, a Professor of solid-state physics at Islamic Azad University, Iran, with over 25 years of academic experience. In addition, I am Senior Consultant & Chair, Scientific Committee of BMF Science Group, Germany (A remote work). I was born on 1972. I obtained my Ph.D. from the University of Malaya, Malaysia (2007–2011), and my research focuses on Nanotechnology, particularly in semiconductor nanocomposites for photocatalytic applications in water treatment and water splitting. Additionally, I explore the use of nanostructures for gas sensors and other advanced applications. Throughout my career, I have published over 150 peer-reviewed papers in high-impact journals and contributed to several book chapters published by Elsevier, Wiley, and Springer. My research has received more than 10,000 citations, with a current h-index of 51 (based on Google Scholar). I have successfully supervised multiple Ph.D. and master’s students, guiding their research in cutting-edge areas of nanotechnology. Beyond academia, I have actively collaborated with industry to develop practical applications of nanostructures, bridging the gap between research and realworld implementation. I have presented my work at numerous international conferences and have contributed to the scientific community as an editor for several journals and a reviewer for numerous ISI-indexed journals. I am honored to share that, for the fifth consecutive year (2021-2025), I have been recognized among the world’s top 2% of scientists in the field of Applied Physics. This recognition is based on data verified and published by Elsevier and Stanford University’s Top 2% Scientists list (2021-2025).
