Dr Dannielle Green

Associate Professor
Faculty of Science and Engineering
Life Sciences
Areas of Expertise:
Animal and environmental biology
Research Supervision:

Dannielle is an Ecologist, interested in all aspects of ecology but her main research focus has been on examining how human activities affect the health of individual organisms and the biodiversity and functioning of marine habitats.

[email protected]


Dannielle joined the Department of Biology in October 2016. From 2013-2015 she was a Researcher at Trinity College Dublin in Ireland and at the University of Warwick from 2015-2016.

She completed an undergraduate degree in Marine Science at the University of Sydney in Australia, specialising in rocky shore ecology for her final year project.

Enthused by the thrill of research, she moved to University College Dublin in Ireland and completed a PhD on the ecological impacts of invasive oysters. After this she won research funding from the British Ecological Society and the Irish Research Council and conducted research on climate change and plastic pollution in marine ecosystems.

Throughout her research career she has discovered that the best way to tackle complex environmental issues is to use an interdisciplinary approach. She collaborates with people from both within and outside the field of ecology in order to link traditional ecological methods with innovative, interdisciplinary approaches from other fields including Biogeochemistry, Ecophysiology and Molecular Biology. The ultimate aim of her research is to provide scientifically sound recommendations for environmental management, influencing policy and protecting marine ecosystems.

Research interests
  • Biological and ecological Impacts of environmental stressors, such as pollution (including plastics and microplastics), climate change, invasive species or urbanisation
  • Biodiversity and ecosystem functioning relationships
  • Biogeochemistry of marine sediments (nutrient cycling)
  • Ecology of the marine benthos
  • Generality across terrestrial, freshwater and marine systems

Dannielle is the Director of our Applied Ecology Research Group.
