Yoonjung Yi

Yoonjung is principally interested in behavioural ecology, especially social interactions of primates, such as inter-group interactions, pair-bond, parenting and behavioral development. She mainly studies these subjects in a pair-living primate, the Javan gibbon (Hylobates moloch) in Java, Indonesia.

Yoonjung主要对行为生态学感兴趣,特别是灵长类动物的社会交互行为,如群体间互动、配对关系、养育后代和行为发育。她的主要研究对象是一对来自印度尼西亚爪洼的活体爪洼长臂猿(Hylobates moloch)

Yoonjung received her Ph.D. from Ewha Woman’s University in the Republic of Korea. During the course of her studies she alternated between staying in Seoul and at the field station in Gunung-Halimun National park in Java, Indonesia. Recently she is also working on interactions between pollinators in China.
