Prof. Akrajas Ali Umar received his PhD in Physics from the National University of Malaysia in 2004 in organic thin film for optical sensing application. He is currently Professor in the Institute of Microengineering and Nanoelectronics (IMEN), the National University of Malaysia since 2011. His research interests are mainly in the field of Nanophysics and Nanomaterial Chemistry, particularly nanostructures design with controlled atomic composition, surface structure and morphology with emphasis on energy conversion applications. Prior to joining the National University of Malaysia, he has served as a lecturer at the Department of Physics, Universitas Andalas, Indonesia from 1997 to 2008. He has also served as Ministry of Science and Technology and Environment of Malaysia (MOSTE) Postdoctoral Fellow, at the National University of Malaysia in 2004, Kyoto University Venture Business Laboratory Postdoctoral Fellow (2004-2005) and Japan Society for the Promotion of Science (JSPS) Postdoctoral Fellow in Kyoto University, Japan, from 2005-2007. He was World Class Professor of Ministry of Research, Science , Technology and higher Education of Indonesia (2018) and visiting scholar in Fudan University, China (2019-2020). He has been appointed as Fudan Scholar, Fudan University in 2023. He has published more than 280 papers in high-impact factor journals with h-index as high as 36.
