ryanRyan Chisholm
Principal Investigator (Office: S3-01-11)

Ryan is a theoretical ecologist with an interest in tropical forest ecology, biodiversity, ecosystem function, and ecosystem services. He completed an undergraduate degree in Mathematics & Statistics at the University of Melbourne and a PhD in Ecology & Evolutionary Biology at Princeton University. Current major research projects aim to understand the mechanisms responsible for large-scale patterns of tree diversity in tropical forests and to explore how this diversity influences ecosystem function. Download Ryan’s CV here.

takTak Fung
Post-doctoral 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 currently working on models of tropical rainforests that aim to (1) quantify how speciation, immigration, dispersal and demographic stochasticity interact to alter the richness-productivity relationship and (2) establish the importance of environmental stochasticity in producing spatiotemporal patterns of species abundances commensurate with empirical data. More details on Tak can be found at his personal website.

nadiahNadiah Kristensen

Nadiah is a theoretical ecologist working in dynamical systems modelling. She is currently focussing on food web models and eco-evolutionary models. She is funded by University Queensland (Centre of Excellence for Environmental Decisions) and the Nature Conservancy.

catharina

Catharina Karlsson
PhD student

Catharina is interested in amphibian biology and conservation. In her PhD, she will use quantitative modelling tools to evaluate conservation strategies for amphibians in Southeast Asia.

deepthi

Deepthi Chimalakonda
PhD student

Deepthi’s research interests lie in metapopulation ecology and wetland birds, with a special focus on wetland conservation. She has a Masters in Wildlife Biology and Conservation from the National Centre for Biological Sciences, Bangalore. For her PhD, she will combine field research and mathematical modeling to a) determine the patterns of wetland bird diversity in man-made wetlands of highly populous agrarian landscapes; and b) investigate and understand the processes behind these patterns. She hopes to start a long-term monitoring project of wetland birds in select sites by building a team of committed birdwatchers and other individuals.

lahiru

Lahiru Wijedasa
PhD student

Lahiru is interested in land-use change, taxonomy and conservation issues. His PhD project addresses land-use change and conservation in Southeast Asia, with a particular focus on plants and peat swamp forest.

aloysius

Aloysius Teo
PhD student

Aloysius is interested in the efficiency of ecosystem processes within different types of tropical regrowth forest, with a particular focus on carbon and nutrient cycling. He is estimating rates of litterfall and decomposition within forests in Singapore and assessing abiotic and biotic drivers of these processes.

sam

Sam Thompson
PhD student

Sam is a joint NUS–Imperial student and his research interests lie in answering large-scale ecological questions, in particular using neutral theory. He has a Masters in Computational Methods in Ecology and Evolution from Imperial College London. For his PhD he will be using coalescence simulation methods to investigate the effect of forest fragmentation on biodiversity.

Jayasri Srikantan

Jayasri Srikantan
Masters student

Jayasri is interested in studying the social behaviour of non-human primates and conflict management of urban wildlife. For her masters in science communication, she will be investigating human acceptance and tolerance of long-tailed macaques (Macaca fascicularis) in Singapore. She will evaluate the effectiveness of public guided walks about macaques to alleviate human–macaque conflict.

Bernard Koh

Bernard Koh
Honours student

Bernard is an Honours student investigating the mechanisms responsible for maintenance of diversity of coral reefs. His project involves the application of mathematical models to data from coral reef communities from around the world.

Lin Yunian

Lin Yunian
Honours student

Lin Yunian is an Honours student in the Bachelor of Environmental Studies. He is assessing the efficacy of Singapore’s Intertidal Watch citizen scientist programme by comparing the citizen scientists’ survey data to data collected by professional scientists.

Wai Yin

Wong Wai Yin
Honours student

Wai Yin is an Honours student studying amphibian calls in Kinabalu Park in Malaysia using acoustic data. Her project aims to assess whether amphibian species have preferred acoustic niches in relation to temperature, humidity and altitude.

Melissa Wong

Melissa Wong
Honours student

Melissa Wong is an Honours student studying island biogeography of birds. Specifically, she is investigating whether statistical techniques can be used to identify distinct guilds of birds within archipelagos.
