Ryan Chisholm
Associate Professor (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 estimate extinction rates in the tropics.

Tak Fung
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.
Nadiah Kristensen
Research Fellow
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.
Deon Lum
Research Assistant
Deon is a research assistant who is working on an analysis of rates of discovery of phylogenetic diversity in birds, and on questions of sample completeness in spatially structured forest inventories.
Hyee Shynn Lim
Research Assistant
Shynn completed her BSc at the University of Plymouth in the UK, and is now working as a research assistant in our lab. She is working on the Sundaland bird biogeography project, in collaboration with Frank Rheindt’s lab. She is also working on models of habitat fragmentation and species diversity.
Mao Yu Qi
Honours student
Yu Qi is an undergraduate student who is working on her Honours project. She is carrying out a population viability analysis for macaques in Singapore.
Sim Hong Jhun
Honours student
Hong Jhun is an undergraduate student who is working on his Honours project. He is jointly supervised by Dr Chong Kwek Yan. His project involves extending the resource conversion model recently published by Ryan and Lam Weng Ngai.
Tricia Cho
Trainee
Tricia recently graduated from the department with a BSc and is currently a trainee in our lab (under the Resilience and Growth Initiative). She is working on an updated analysis of bird extinctions in Singapore.
Guan Tong
Undergraduate Research Opportunities Programme in Science (UROPS) student
Guan Tong is a third-year undergraduate student doing her UROPS project on modelling the COVID-19 epidemic in Singapore.
