Senior Research Ecologist

Office:
Stirling
Nina is a Senior Research Ecologist and part of the Wetland and Marine Research Team, based within BTO Scotland. Her role involves reporting, analysis and fieldwork with a focus on marine birds.
Nina has a broad interest in ornithology and conservation, with a particular interest in anthropogenic threats to marine birds and their environment.
Nina also has a background in seabird foraging ecology and movement behaviour, which has involved a range of fieldwork and analysing large datasets. The skills and experience gained from her previous positions fit well with the seabird work of the Wetland & Marine Research Team.
