Marine Sciences explores how ecological communities respond to environmental change across coral reefs, deep-sea ecosystems, and marine mammal populations. Research within the group combines ecological theory, mathematical modelling, and field-based approaches to understand how marine systems are organised across space and time.

Current work includes the development of stochastic state-and-transition models to forecast successional change within benthic coral reef communities under accelerating climate pressure. Other projects investigate biodiversity and governance in the deep sea of the Western Indian Ocean, combining ecological research with policy analysis to address major knowledge and capacity gaps across Small Island Developing States.

Research on pinniped population dynamics examines how marine mammal populations recover following commercial exploitation and respond to environmental variability such as El Niño events. Using Bayesian frameworks, matrix population models, and drone-based biometric surveys, these projects investigate resilience, extinction risk, and physiological responses to climate-driven disturbance.

Together, this work examines marine ecosystems across scales, from community organisation and ocean governance to population viability and individual condition.
