Who We Are

Founded in January 2016, the Langur Project Penang (LPP) is an outreach research and conservation project under the umbrella of the Malaysian Primatology Society (MPS) and Universiti Sains Malaysia (USM). In collaboration with governmental bodies, educational institutions and Non-Governmental Organizations (NGO) in Malaysia, LPP serves as a platform for environmental research and education for students and the local community. We are looking to amplify its voice for the Dusky Langurs by preserving Dusky Langurs’ natural habitat, continuing to battle the illegal wildlife trade, and by keeping as a crucial platform for research and outreach programmes in Penang.

LPP is founded by Jo Leen Yap, a wildlife researcher and environmental educator, studying the ecology and behaviour of Dusky Langurs (Trachypithecus obscurus) in Penang. As a PhD student of Universiti Sains Malaysia, she founded Langur Project Penang (LPP) back in January 2016, with the aim to motivate and inspire local community involvement in primate conservation and nature education.  Expected to complete her thesis in 2021, Jo Leen has the vision to further bridge the gap between primate conservation and community engagement in Malaysia. With her enthusiasm, positive and creative mindset, Jo Leen is always on-the-go, thinking for the dusky langurs, for her team members, in order to sustain LPP as a long-term community science platform in Malaysia.
