Dr. Likarn Wang was born in Taiwan, Republic of China, in 1959. He graduated ,in 1981, from the Department of Electrical Engineering (B.S.),National Tsing Hua University, and then graduated from the same department with the master degree in 1983. After two-year military service, he went to U.S.A. for further study. In 1989 he obtained the Ph.D. degree in Electrical Engineering at The Pennsylvania State University. In 1990 he started his education/research career at National Tsing Hua University. He is now a professor of Department of Electrical Engineering at the same school. He specializes in the subjects of optical fiber communications, waveguide optics and optical fiber sensors.
