Professional biography

I am an organic geochemist who works on inter-disciplinary problems within Earth and environmental science. I am currently Principal Investigator on a NERC funded project entitled " 500,000 years of solar irradiance, climate and vegetation change". Previously I have been Principle Investigator of a project funded by the the Royal Society investigating "intra- and inter-species relationships of sporopollenin".

Research interests

My research interests are broadly unified by a link withultraviolet (UV) radiation, including the development of a biogeochemical proxy for UV radiation through time and space, UV-stimulated methane emissions from vegetation, and the potential atmospheric impact of degrading plastics in the environment.

I also have a keen interest in understanding the long-term chemical stability of biopolymers in the geological record, and the development, evolutionary preservation and structural commonality of the biopolymer sporopollenin in terrestrial plants.

Latest research developments have seen me start to explore fast analytical methods for accessing geochemical locked within sedimentary cores, and the application of geochemical analyses to address archaeological questions.

Teaching interests

My teaching interests span a broad range covering atmospheric and climate science, the use of biogeochemical indicators of past environmental change, and the hydrology of ephemeral channels in arid and semi-arid regions.
