Indra Karnadi (email@example.com) received his Ph.D. in 2015 in Physics from Korea Advanced Institute of Science and Technology (KAIST) with a focus on the integration of III-V nanobeam photonic crystal laser on silicon susbstrate and fiber optics under the supervision of Prof. Yong-Hee Lee. Upon completion of his Ph.D., he worked as a postdoctoral researcher in the Department of Material Science and Engineering, KAIST. Currently, he is an assistant professor at the Electrical Engineering Department of Krida Wacana Christian University (UKRIDA). Since 2017, he has been actively involved in research on laser-induced breakdown spectroscopy (LIBS) at the Maju Makmur Mandiri Research Center. He has authored and co-authored more than 20 peer-reviewed international journals. His current research interests include photonic crystal, plasmonic nanoparticle, and laser-induced breakdown spectroscopy. He is an active member of the Indonesian Optical Society and the Optical Society of America.
