Stacey's research

Dr Stacey Trevathan Tackett is a marine scientist who specialises in wetland soil carbon and function. Her multidisciplinary research integrates fundamental and applied research approaches to ensure that wetland preservation and restoration outcomes are based on robust and novel research discovery. Stacey’s research interests include seagrass wasting disease, plant and soil decomposition, how microbe-carbon interactions regulate carbon preservation and storage, and improving soil, plant and microbiome function in response to restoration actions.
