Community and movement ecology of marine predators

1
Testing ecological and behavioural theory to look at the role of processes like competition and intraguild predation in structuring predator distributions.
2
Understanding drivers of habitat selection and movements in predators.
3
 Linking individual animal movements to population level processes. 
4
Testing how fish transfer nutrients across habitats.

Behavioural and physiological adaptations in marine predators

1
Investigating the physiology of digestion in sharks to understand prey breakdown and assimilation.
2
Studying how predators tailor swim speed and diving behaviour to optimize metabolic processes in the marine ecosystem.

Fisheries, fin trade, and applied conservation

1
Using anal fins to understand the species and size composition of the Belizean shark fishery.
2
Identifying the species composition of the Hong Kong shark fin trade.
3
Developing real-time genetic tests to assist customs officials in cracking down on illegal wildlife trade.
4
Training and funding Belizean fishers to assist with scientific data collection in order to reduce fishing pressure in areas where shark populations have recently declined.
5
Communicating results from our Global FinPrint project, the world's largest shark and ray survey on coral reefs, to local stakeholders in order to improve management of threatened species.
