 Biographical Sketch
Dooyoung Hah was born in Seoul, Korea. He received his B.S.(1994), M.S.(1996), and Ph.D.(2000) degrees all in Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST). Professor Songcheol Hong has been his advisor during his graduate study. He continued his research at the Integrated Photonics Laboratory (IPL), University of California, Los Angeles (UCLA) as a Research Associate under supervision of Professor Ming C. Wu (now at UC Berkeley). He also has worked at the Electronics and Telecommunications Research Institute (ETRI), Korea as a Senior Member of Research Staff. Currently, he is an Assistant Professor of Electrical and Computer Engineering at Louisiana State University, Baton Rouge.
