Given the abundance and diversity of frogs in the tropics, the bi-phasic life history of most frogs (terrestrial insectivorous adults and aquatic herbivorous tadpoles), and the central role of frogs in food webs (almost everything eats frogs and frogs eat nearly anything that fits in their mouths), we also have good reason to use frogs as a model study system across time and space.

Current and future projects focus on:

1) comparing historical and current species assemblages to answer questions about the impacts of climate change

2) comparing stream and forest assemblages of frogs across the archipelago and mainland with many questions in mind (systematics, cryptic speciation, species assemblage rules, community and assemblage structure, habitat specialization, and species assemblage influences on reproduction, survival, and microhabitat partitioning)

3) monitoring assemblage changes and species specific responses to logging, different forest management strategies, disturbance, fragmentation, and access to breeding sites


4) assessing the amphibian and reptile trade. Comparing harvested and non-harvested populations in terms of reproductive ecology and population demographics to quantify the sustainability of current commercial exploitation and determine population viability

5) determining the most important local, regional, and global drivers of extinction risk and

6) measuring the relative importance of those drivers across a range of different environmental and biotic gradients with the end goal being a more comprehensive and sensible conservation strategy for amphibians


Prospective Students

I welcome Masters and Ph.D. students to join the Evolutionary Ecology and Conservation lab.  I have expertise working with amphibians and reptiles, but can advise students who want to work on virtually any aspects of evolutionary ecology and/ or conservation.  Projects could focus on region-level questions or individual species, biogeography, phylogenetics, behavior, ecology, or multi-disciplinary approaches to help solve conservation issues.  For more information, please see the NUS Faculty of Science graduate admissions website for application:
