Principal Investigator (Office: S3-01-11)
Ryan is a theoretical ecologist with an interest in tropical forest ecology and biodiversity. 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.

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.
Nadiah is a theoretical ecologist with broad interests in dynamical systems. She is currently working on models for estimating species extinction rates from incomplete data, as part of our lab’s Singapore extinctions project, and also on models of social evolution. More details on Nadiah can be found at her personal website.
Senior Research Fellow
Martin is a physicist with a background in quantum mechanics and density functional theory. Martin holds a 50% appointment in our lab and is applying techniques from theoretical physics to study complex ecological systems, with a particular focus on models of temporal environmental variance.
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.
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 is using coalescence simulation methods to investigate the effect of forest fragmentation on biodiversity.
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 combined 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 started a long-term monitoring project of wetland birds in select sites by building a team of committed birdwatchers and other individuals.
Meryl is a research assistant working on both our island biogeography project and our Singapore extinctions project.
Deon is a research assistant who is applying our extinction models to data sets of mammals and birds from Australia
Deborah is an Honours student working on a population viability analysis of the Straw-headed Bulbul in Singapore. The Straw-headed Bulbul is found in Peninsular Malaysia and Borneo, and is classified as endangered. One of its strongholds is Singapore, where the incidence of hunting and trapping is low.
Chris Wei Ziyi
Chris is an Honours student working on our Singapore extinctions project. He is looking at species traits associated with extinctions over the past 200 years in Singapore. He is focussing on birds and mammals.
