Jonathan earned his PhD in 2014 focusing on the feeding and sensory ecology of South East Asian colobines. Specifically, he is looking at habitat variation within black shanked doucs (Pygathrix nigripes) and the status of silvered langurs (Trachypithecus margarita) in Cat Tien National Park, Vietnam. His work focuses on the conservation of primates within Vietnam and the surrounding region.
Cat Tien National Park is located 150 km from Ho Chi Minh City in the south of Vietnam. This site is one of the last remaining lowland evergreen forests in Vietnam. Over the past three years Jonathan has been living and working in Vietnam collecting his dissertation data. In addition to this research he has had the opportunity to work with the Center for Biodiversity in Ho Chi Minh City conducting biodiversity studies at Ta Kou Mountain, as well as working with Free the Bears and Wildlife at Risk.
Over the past five years, Jonathan has worked with primates in captivity outside of Hanoi, Vietnam in Cuc Phuong National Park at the Endangered Primate Rescue Center before working with wild populations of animals in the south of Vietnam.
