Mati Horprathum received Ph.D. degree in Physics from King Mongkut’s University of Technology Thonburi (KMUTT), Thailand in 2009. In 2011, he received a postdoctoral fellowship supported by Japan National Project “the Funding Program for Next Generation Word-Leading Researcher.” During the postdoctoral position, he worked at Laboratory of Atomic Scale Materials Processing, Institute of Scientific and Industrial Research (ISIR), Osaka University, Japan in the “Green Innovation Science” project. He is now a senior researcher and the team leader of opto-electrochemical sensing research team (OEC), spectroscopic and sensing devices research unit, NECTEC, Thailand. His current works involve nanomaterial devices areas, i.e., nanostructure plasmonic sensor, optoelectronic devices, fabrications and characterizations of nanostructures, and spectroscopic ellipsometry. Through his career, his major interests are to utilize the thin-film and nanostructure technologies towards local industrial manufactures, as well as medical and environmental applications in Thailand. He also enjoys giving lectures in the optical thin-film and nanotechnology to undergraduate and graduate students, and engineers working on optical and hard disk drive industries in Thailand. In addition, he was awarded the 2016 ICO/ICTP Gallieno Denardo Award from the International Commission for Optics (ICO) and the Abdus Salam International Centre for Theoretical Physics (ICTP).
