Professor (Office: S3-01-11)
Ryan is a theoretical ecologist with interests in tropical forest ecology and biodiversity. Current major research projects aim to understand the mechanisms responsible for large-scale patterns of tree diversity in tropical forests and to estimate extinction rates in the tropics.

Tak Fung
Senior Research Fellow
Tak constructs and uses mathematical models to investigate processes governing population dynamics in complex ecosystems. He studied Mathematics at Imperial College London as an undergraduate, before doing two PhDs at University College London and Queen’s University Belfast, on modelling the dynamics of coral reef and temperate marine shelf ecosystems. Tak is working on a range of projects including models of tropical forest dynamics and population viability analysis of focal species in Singapore.
Liu Fang
Research Fellow
Liu Fang specialises in behavioral and experimental economics, having earnt her PhD from Nanyang Technological University. Her research explores the emergence and evolution of cooperation, social identity, and norms within networks. By bridging evolutionary insights with contemporary issues of identity and coordination, her work addresses the complexities of diverse societies. She is currently investigating the evolutionary dynamics of punishment.
Sankar Ananthanarayanan
PhD Student
Sankar is a PhD student who graduated with a BSc (Hons.) in Life Sciences from NUS in 2019. He is interested in applying population viability analysis to reptiles in rapidly changing Southeast Asian landscapes. He hopes such studies can provide key insights into developing conservation and reintroduction strategies for these creatures.
Ho Ning
PhD Student
Ho Ning is a PhD student interested in exploring the anthropogenic factors that influence population ecology, hoping to advance and drive better-informed and holistic conservation efforts. Broadly, she is also interested in the multi-faceted relationship between the natural environment and the public.
Zhu Mingyi
PhD Student
Mingyi is a PhD student currently interested in the mechanisms underlying biodiversity as well as evolutionary game theory. He believes there are similarities and common grounds that can be found between these two seemingly unrelated fields.
Randall Ho
PhD Student
Randall is a PhD student looking at applications of genomics to invasion biology. He was previously an Honours student in the lab.
Angelica See
PhD Student
Angelica is interested in studying the effects of habitat fragmentation on tropical ecosystems. She graduated with an environmental science degree specialising in ecology from Nanyang Technological University. Her main supervisor is Junying Lim in the Plant Ecology, Evolution & Biogeography Lab.
Jiang Zhiyi
Visiting PhD Student
Jiang Zhiyi is a visiting student from Zhejiang University. Her research focuses on how habitat fragmentation influences biological invasions, using the spread of pine wilt disease in the Thousand Island Lake as a case study.
Chiok Wen Xuan
Master’s Student
Wen Xuan (Shane) is a 2019 lab alumnus, now a returning Master’s student. His work has spanned academia, government, NGO, and environmental consultancy, and he sits at the interface of research, policy, and applied conservation, with Southeast Asian fauna and habitats as the common thread. He now hopes to draw on this blended experience to assess vertebrate conservation priorities across Southeast Asian landscapes, coupling ecological modelling with green finance metrics to produce conservation outputs with real-world impact.
Hou Yunhan
Master’s Student
Yunhan is a Master’s student who is also working as a Research Assistant in the lab. He is researching the status of the Sunda pangolin in Singapore and modelling population viability of migratory shorebirds.
Tricia Cho
Master’s Student
Tricia is a part-time Master’s student based primarily in the Freshwater and Invasion Biology lab. She is a research assistant at the Lee Kong Chian Natural History Museum, working on the SIGNIFY project. Her Master’s project aims to study dark extinctions among freshwater taxa in Singapore and Southeast Asia.
