Biography
Professor Aya received his Ph.D. degree in materials engineering from Tokyo Institute of Technology in 2014 under the supervision of Prof. Hideo Takezoe and Prof. Ken Ishikawa. He has been a professor at South China University of Technology in China since 2019. His principal interests are the physicochemical properties of soft matter, particularly in fundamental physics and electroopitcs in traditional liquid crystals, polar liquid crystals, colloids, and elastomers, etc. He is a member of The International Liquid Crystal Society (ILCS), The International Society for Optics and Photonics (SPIE), The Physical Society of Japan (JPS) and The Chinese Physical Society (CPS).
Research Interests
Our group are dedicated to understanding and creating topology-mediated structures in soft matter systems, focusing particularly on the new polar liquid crystals, colloids, and elastomers. By leveraging the principles of soft matter physics and modern optics, our research seeks to reveal groundbreaking phase behaviors and exceptional electro-optic properties that surpass traditional understandings. Through rigorous experimental physics and advanced simulations, we aspire to design and seamlessly integrate fluidic soft-matter materials into advanced flexible electro-optic devices, paving the way for the next generation of smart electronics and precise optical manipulation.
