Profile
Kota Kumagai is an assistant professor in Center for Optical Research and Education (CORE) of Utsunomiya University since 2020. He received a Ph.D. in Engineering from Utsunomiya University in 2019 with a President's Award 2018 via JSPS Research Fellow DC1 and research inter at Swinburne University of Technology. From 2019 to 2020, he has worked for R&D Center of Sony Corporation. His research interest is an intersection of optics and information engineering, and recently, focused on volumetric display and computational imaging with femtosecond laser-matter interactions. He received a Good Design Award 2015 and a JSPS Ikushi Prize in 2018.
