David is quantitative palaeoecologist, specialising in the study of diatoms (siliceous microalgae) in a wide range of aquatic environments from inland freshwater and saline lakes, to coastal fjords and lagoons. His main research interest lies in using sediment records from lakes, fjords and estuaries to explore the nature of past environmental change under changing climatic regimes and cultural impacts. Key research interests focus on a long-term perspective on the development, variability and response of aquatic environments and nutrient cycles (Si, C, P) to both natural and anthropogenic drivers (e.g. eutrophication) on inland and coastal systems. As well as in the UK, he has worked on sites in North America, Italy, Denmark, Greenland, Siberia (Lake Baikal) and eastern Africa (Uganda, Ethiopia) supported by funding including from NERC, the Leverhulme Trust, NSF, Danida and the Carlsberg Foundation.

One theme running through his research is the critical analysis of palaeoenvironmental data and methodologies. He is especially interested in the transformation of living diatom communities to fossil assemblages, using limnological monitoring, sediment traps and experimental study data to inform and improve palaeoenvironmental inferences. More recent NERC-funded research has focussed on testing the application of stable isotopes in diatom silica (18O and 30Si) as proxies for lake hydrology and productivity; and changes in the marine environment over key periods in the Holocene, including a project funded by the Leverhulme Trust combining archaeological and environmental science in Danish Baltic coastal sites to test hypotheses concerning human diet and patterns of subsistence.

David's teaching focusses on the hydrology of lakes and rivers, with more specialised modules in lake system dynamics, environmental change and palaeoecology (the study of past ecosystems, and especially lakes: palaeolimnology).
