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. Download Ryan’s CV here.

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 epidemiological models of dengue in Singapore. 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 applications of evolutionary game theory to conservation problems. More details on Nadiah can be found at her personal website.

Nicolás Firbas
PhD Student

Nicolás did his undergraduate degree at Rutgers State University of New Jersey in statistics with a minor in entomology. Afterwards he obtained an MA in mathematics from a joint program between the Universitat de València and Universitat Politècnica de València with a thesis on machine learning methods for description of anomalous diffusion. Nicolás is broadly interested in mathematical modelling of ecological systems.

Sean Pang
PhD Student

Sean is completing the final year of his PhD, and was until recently a student in the lab of Ted Webb, who has now moved to the University of Helsinki. Sean’s interests revolve around spatial ecology and he is currently focussed on species distribution modelling and related methodological questions, such as the effect of various methods of variable selection on temporal transferability of the models, and the effects of different land-use change maps on model performance and prediction. His ecological interests include the effect of climate change on the distribution patterns of trees in the tropics. He is also interested in the eventual conservation planning recommendations that may come from these models.

Hyee Shynn Lim
Research Assistant

Shynn completed her BSc at the University of Plymouth in the UK, and is now working as a research and teaching assistant in our lab. Her research concerns models of habitat fragmentation and species diversity.
