Dr Heidi Burdett is a Research Fellow at the Lyell Centre for Earth and Marine Science and Technology. Before joining the Lyell Centre, Heidi worked as an Associate Ediator for Nature Microbiology, having previously held a research fellowship at the University of St Andrews. Heidi completed a PhD in Marine Science at the University of Glasgow in 2007, investigating the sulphur biogeochemistry of coralline algal habitats, and its relationship to photosynthesis. Heidi adopts a multi-disciplinary approach to investigate how marine photosynthetic organisms (e.g. algae, seagrasses, corals) affect, and are affected by, the environment in which they live. This is considered within the context of natural environmental variability (e.g. daily, seasonal and annual cycles) and future climate change, especially ocean warming, acidification and deoxygenation. Heidi is also seeking to define the limits of photosynthesis, and the impact this has on our understanding of marine biogeochemistry, resource provision and conservation, and the translation of marine science into industry.
