Ryota Kabe

Dr. Ryota Kabe is an Associate Professor at the Okinawa Institute of Science and Technology Graduate University (OIST), where he leads the Organic Optoelectronics Unit. He earned his B.Sc. from Kansai University (2005), M.Sc. from Osaka University (2007), and Ph.D. from Kyushu University (2010). 

Following his doctoral studies, Dr. Kabe pursued postdoctoral research at Bowling Green State University (2010–2011), the Max Planck Institute for Polymer Research (2011–2012), and Kyushu University (2012–2014). He subsequently served as an Assistant Professor at Kyushu University (2014–2019), working in collaboration with Prof. Chihaya Adachi. 

In 2019, he joined OIST, where he continues to advance research in organic optoelectronics. His work focuses on the design and synthesis of novel organic materials, the manipulation of organic exciton dynamics, and their application in next-generation optoelectronic devices.
