My research aims to identify and understand processes and mechanisms by which shellfish populations adapt and change, and how coastal marine food production systems interact with the broader marine ecosystem. It focuses on shellfish fisheries and aquaculture; a useful model system because the adult (exploited) phase of the life cycle is sessile, whilst the larval stages are mobile and highly dispersive. This dispersive larval strategy is common among many marine species, and thus makes my research relevant well beyond species of commercial interest. Additionally, shellfish are often considered important ecosystem components because of their role as filter feeders and ecosystem engineers that alter or provide habitat for other species. As human populations grow and pressure on our coastal and marine ecosystems for food and other resources expand, it will become increasingly important for sustainable management of industries such as shellfisheries and aquaculture, planning marine protected areas, and predicting impacts of climate change.
