Biography

Kun-Yu (Alvin) Lai is currently a professor in the Department of Optics and Photonics at National Central University (NCU) in Taiwan. Dr. Lai received his Ph.D. degree in Electrical Engineering from North Carolina State University in 2009. After working as the postdoctoral fellow in the Graduate Institute of Photonics and Optoelectronics at National Taiwan University in 2009-2011, he joined the faculty in the Department of Optics and Photonics at NCU, where he specialized in the growth/fabrication of novel III-nitrides optoelectronic devices and the optical properties of low-dimensional structures, such as quantum wells and nanowires.
