Profile

Research Overview:

Debbie is a quantitative marine ecologist with a particular interest in the interactions between marine predators and their natural versus anthropogenic environment. She is based at SMRU where the focus of her research can be split into two inter-linked components (1) Conduct, manage and communicate research that is required to inform sustainable management of UK seal populations, and to fulfil national and international conservation legislation (see SCOS) (2) Gain critical insight into emerging conservation and management issues through external funding for projects which provide understanding of the drivers of marine predator behaviour, distribution and population dynamics.  

 

Key research areas (see Group for more)

• Estimation of seal abundance and trends on land, and drivers therein
• Estimation of seal distribution at-sea, and drivers therein
• Using a mixture of Bayesian and frequentist methods to analyse harbour and grey seal telemetry data to answer both pure and applied research questions.
• Investigation of the impact of anthropogenic structures, their construction, operation and decommisioning, on marine predators. EcoSTAR project
