My research focuses on assessing the effects of fisheries and the environment on population dynamics, community structure and marine ecosystem functioning, in the context of implementing a more ecosystem-based fisheries management.
My research focuses on a regional spatial scale (Celtic Sea).
I am also interested in better understanding individual and collective skills in the processes of fish escape in fishing gear (Applied Ethology).
