I hold a Ph.D. in Biological Anthropology from the University of Colorado Boulder (CU Boulder). My research interest lies in the ecology, behaviour, and population genetics of Asian colobines (langurs and odd-nosed monkeys). Specifically I study the Raffles' banded langurs in Singapore and Malaysia, Tonkin snub-nosed monkeys, Indochinese silvered langurs and black-shanked doucs in Vietnam, and have previously studied the white-handed gibbons in Thailand.

Oct 2019 | Great Women of Our Time Award for Science and Technology


The annual Great Women of Our Time awards presented by Women's Weekly magazine celebrate Singapore's inspiring women who contribute positive change to the society in different fields such as Science and Technology, Arts and Media, and Finance and Commerce. 

Thank you for honouring my work in environmental and wildlife conservation at this year's award for Science and Technology! 

I dedicate this award to the late Mr. Subaraj Rajathurai, who was one of Singapore's greatest nature warriors and my inspiration.

May 2018 | Appointed as President of Jane Goodall Institute (Singapore)


The Jane Goodall Institute (Singapore) was founded in 2007 to continue Dr. Jane's work with humans, animals and the environment. 


Despite being a small island of almost 720 sq km, Singapore is home to rich biodiversity. However as with other highly urbanized countries and developing nations, human-wildlife conflict is a serious concern in the space-limited Singapore. 


As the President, I hope to help further Dr. Jane's goal of promoting wildlife conservation and environmental stewardship.

Short Film 2012 | Conserving Colobines: Saving Endangered Leaf Monkeys in Vietnam


With 25 species of primates, Vietnam has one of the highest primate diversities in Southeast Asia. The country is also home to over 92 million people.


Conservation is not easy.


In coordination with local conservation groups, I hope to learn more about and help protect these primates.

TEDxNUS (Singapore) 2011 | Raffles' Banded Langurs in Singapore


The Raffles' banded langur (Presbytis femoralis femoralis) is critically endangered in Singapore. Yet, there was little information on its ecology and behavior. Here I share some of my M.Sc. research findings on this species at TEDxNUS in Singapore.
