Research Interests

Coral reef rehabilitation, coral reef ecology, environmental management

Current Research

Coral reefs are threatened and declining rapidly due to a myriad of stressors. Restoration can assist in improving the resilience of these ecosystems, but such efforts can be costly and hindered by resource limitations. My research focuses on the functional characterization of corals in Singapore. Using a trait-based approach, species that contribute more to reinstating the functions and ecological value of degraded reef areas can be identified, thus facilitating the formulation of more effective restoration strategies.
