Ahmad Rifqi Md Zain is an associate professor of electronics engineering at the Institute of Microengineering and Naoelectronics (IMEN), Universiti Kebangsaan Malaysia (UKM). He received his Bachelor’s degree and Master’s degree from Coventry University and Glasgow University, United Kingdom, in 2002 and 2005, respectively. Ahmad Rifqi also worked with Marconi Communication as a hardware engineer United Kingdom from 2002–2004 before pursuing his study at Glasgow university. In 2009, he received his Ph.D. from Glasgow University, United Kingdom (with Prof Richard De La Rue), in Electronics engineering (1D photonic crystal cavities). After completing his postdoctoral studies in 2012 at Bristol university in gallium nitride-based optical biosensors (with Prof Martin J. Cryan), he joined IMEN, UKM in August 2014. In 2017, he joined Prof Marko Loncar at the School of Engineering and Applied Sciences (SEAS), Harvard University, as a postdoctoral research fellow in applied physics until 2019, working on quantum information. Ahmad Rifqi is an expert in nanophotonics, optoelectronics, and nanofabrication, and his current interests include optical imaging at infra-red region, 2D materials, optical based biosensors, 1D and 2D photonic crystals, optical MEMS sensors, environmental and agricultural based sensors, integrated optics, and nanofabrication. Ahmad Rifqi is a member of the Optical Society of America, IEEE, IET, and SPIE.
