Marine biology, coral reef ecology, giant clams, coastal change, the functions of colour and morphology.
As an ecologist and SCUBA diver it was almost inevitable that I should end up studying coral reefs and coastal systems. 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 crab (the only corals in those chilly waters are deep in the sea)! After returning to Singapore I started working on the autecology of giant clams, the effects of sediments on corals, and other coastal change related issues. Much of my research has involves extensive fieldwork and experimentation, and often requires the development of novel methods and techniques.
