Research Interests
As an ecologist and SCUBA diver it was almost inevitable that I should end up studying coral reefs. I conducted my doctoral research here in Singapore on intraspecific variation, phenotypic plasticity, and symmetry in scleractinian corals. After my PhD I spent two years in Scotland where I focused on crypsis and polymorphism in the shore crab Carcinus maenas (the only corals in those chilly waters are deep in the sea)! Since returning to Singapore I have also been working on the autecology of giant clams. Much of my research has involves extensive fieldwork and experimentation, sometimes requiring the development of novel methods and techniques for investigating morphology, colours/patterns, and behaviour. Data sets are frequently large and complex, making them suitable for exploration with various multivariate analyses.
