Jaeha Ahn and Yena Kim are science communicators who translate scientific ideas into everyday conversation in a uniquely engaging way. Located in Mureung-ri, Daejeong, Jeju, You In One is a science communication café that conveys the message that humans are part of nature, creating a space where people and the environment can learn together. Jaeha began his career studying insects and later expanded his focus to explore entire ecosystems as an ecologist, while Yena, a researcher in animal cognitive behavior, studied great apes and the emotional expressions shared between humans and primates. Sharing the belief that “science begins with everyday curiosity,” the two run youth education programs, exhibitions, and citizen science projects that connect closely with the local community. Among their projects, their projects Recorders of the Western Sea of Jeju and Citibat, a citizen bat-monitoring program, have drawn enthusiastic participation from both students and residents. Bridging science and art, people and nature, You In One continues to explore new ways of learning and communicating from a small village in Jeju.
