Yuki Kondo (Ph.D., Osaka City University, 2022) is a Specially-Appointed Assistant Professor at Osaka Metropolitan University. His research focuses on the behavioral and reproductive ecology of the medaka fish (Oryzias latipes), a vulnerable species in Japan. Combining 24-hour video observation, DeepLabCut-based motion tracking in laboratory tanks, and field surveys in Gifu streams, he has revealed that wild medaka begin spawning around midnight—several hours earlier than reports based on laboratory animals had suggested—and that males adjust their sperm allocation in response to social context. He is a member of the Japan Ethological Society, the Ichthyological Society of Japan, and the Ecological Society of Japan.
