Organisation or Individual Expertise:
General: My research generally involves molecular investigations into natural processes and carbon cycling in marine and terrestrial environments (soil, water and sediment). This means pushing the boundaries of analytical chemistry and also working closely with molecular biologists. At present, we are particularly interested in soil and sediment autotrophy and CO2 uptake. We are also interested in methane and hydrocarbon seeps in marine settings and the unique communities and chemistry present. In most projects we aim to understand the biochemistry and response of living systems to environmental change and learn how to interpret these responses molecularly. The techniques that we use are applicable to other areas of research such as paleo-environmental, hydrocarbon degradation in the environment, energy from biomass and astrobiology and we are very happy to contribute to these projects. Please see some sample papers covering my research of natural organic matter in soil, water and marine sediments below and also a list of the main techniques that we use: SAMPLE PUBLICATIONS: SOIL CARBON DYNAMICS: 1.
