Brief Biography
Tatsushi HAMAGUCHI was born in Osaka, Japan, in 1980. He received his B.S. and M.S. degrees in materials science and engineering from Kyoto University in 2004 and 2006, respectively. He earned his Ph.D. degree in electronic engineering from Sophia University in 2019. From 2006 to 2008, he worked at the Nitride Semiconductor Research Laboratory of Nichia Corporation. After 2008, he joined Sony Corporation, where he led the development of nitride-based edge-emitting lasers and vertical-cavity surface-emitting lasers (VCSELs) as the leader of Sony’s project team. In 2024, he was appointed as a Professor at Mie University and is currently a Professor at Kyushu University.
