Born in 1983, Yumiko Naka is a graduate of the Tokyo University of Science. In 2011, she received her doctorate from the Tokyo Institute of Technology. She then joined Tokyo University of Science as a Research Associate in Professor Takeo Sasaki's laboratory. She then
promoted to an Associate Professor in 2015. She received the CSJ Student
Presentation Award (2009) from the Chemical Society of Japan, Rainbow Award
(2010) from Japanese Liquid Crystal Society and Encouragement Award (2012)
from Japanese Liquid Crystal Society.
Her current research interests include the photorefractive effects of organic
materials and the synthesis of novel functional polymers.
