Prof. Vincent Gauci is a Birmingham Professorial Fellow in the School of Geography, Earth and Environmental Sciences. He is interested in the biogeochemistry of carbon-dense terrestrial ecosystems such as forests, wetlands, peatlands, and forested wetlands and peatlands. In particular he is interested in how these ecosystems interact with the atmosphere through the exchange of greenhouse gases with a particular focus on trace greenhouse gases such as methane and N2O. Vincent Gauci’s new research project (MitiMEN) seeks to identify the response of methane and Nitrous Oxide (N2O) emissions to peatland re-wetting, through a combination of detailed scientific investigation of methane and N2O emission from trees, soils and drainage channels in a Sumatran plantation. This research will help inform future policy decisions such as whether to raise water levels below peat surface to reduce future fire vulnerability of the peat.
Dr Sami Ullah’s research is mainly focused on the biogeochemistry of nitrogen and its linkages to carbon and phosphorus cycling under global change in soils under forest, peatland/wetland, grassland, and agricultural crops. Dr Sami Ullah is involved in a number of research projects which started in 2019/20 including ‘MarshFLux: Greenhouse gases & blue carbon under global change’ and research project ‘MangRoot Research: Getting to the roots of the carbon in mangrove forests: a case study in Vietnam’.
