KhaiQuang Le
Khai Q. Le was born in Khanh Hoa, Vietnam, in 1983. He received a degree in Physics from Ho Chi Minh City National University, College of Natural Sciences, Vietnam, in 2005. From 2006 to 2008, he was with the Nanophotonics group at the Department of Electrical and Computer Engineering, Ajou University, Korea. He is currently working toward the Ph.D. degree in electrical engineering at the Department of Information Technology (INTEC), Ghent University, Belgium. During his PhD study he has spent 3 months at George Green Institute for Electromagnetics Research, University of Nottingham, Nottingham, UK as a visiting scholar to perform the short term scientific mission (STSM) program of COST Action MP0702.
He has research interests in the development of numerical modeling and simulation tools for guided-wave optics and optoelectronics as well as several applications of nanophotonics (optical biosensors, LEDs and solar cells). He serves as a reviewer for international journals including IEEE/OSA Journal of Lightwave Technology, IEEE Photonics Technology Letters, Journal of Optical Society of America A (and B), Optics Express, Optics Letter, Applied Optics, Plasmonics...
