Postgraduate Student Research Projects

Dr Brodie much enjoys working with local and regional postgraduate students, and in partnership with them she has undertaken research on a wide variety of environmental and conservation related projects: including topics related to maintaining ecosystem and economic service benefits from marine, freshwater and forest resources on islands. Dr Brodie has a passion for invertebrates, particularly molluscs, and the habitats they occur in. She is interested in working on projects involving applied or multidisciplinary approaches to sustainable use of natural resources, in particular those with links to policy development, ecosystem service benefits, nature-based solutions, climate change, pollution, biodiversity assessment, taxonomy and the use of invertebrate fauna, including cultural use, by humans.
