Le Khac Quyet is one of the leading field biologists in Vietnam and is pleased to be a member of the IUCN/SSC Primate Specialist Group. He is best known for his work on the Tonkin snub-nosed monkey (Rhinopithecus avunculus), one of the most endangered primates in the world. His accomplishments include confirming the presence of this species in the Khau Ca region of Ha Giang Province, Vietnam in 2002 and in the Tung Ba region of this province in 2007. He has worked continuously in the Khau Ca area since 2002 with a range of stakeholders to study and conserve this species. Outcomes of these efforts include a well-trained group of local research assistants, an enhanced understanding of the ecology of this species, a conservation education program, and most importantly, the establishment of the Tonkin Snub-nosed Monkey Species/Habitat Conservation Area at Khau Ca (Ha Giang Province) that provides protection to the largest remaining population of this Critically Endangered species. In addition, Quyet’s work at Khau Ca has formed the basis of his Master’s Degree from the Vietnam National University, Hanoi earned in 2006 and his PhD Degree from the University of Colorado Boulder earned in 2014. Quyet has extensive field experience across Vietnam, and in addition to working on primates, he has co-authored papers naming three new snake species. He is an extremely talented photographer and enjoys using beautiful nature photos to inspire others to be interested in conservation. Finally, he is a proud husband and loving father to his daughter and son.
