Qualifications & background
 
Oct. 1991 – June 1994: Obtained a 2:1 BSc Honours degree in Geochemistry at the University of St. Andrews on the 7/7/1994. During my degree I spent 2 months conducting my 3rd year undergraduate fieldwork project on the South Rurie Carbonatite Complex in western Kenya.

Sept. 1994 – Jan. 1998: Obtained a PhD from Cardiff University on the 14/7/1998. The thesis title was "Studies of geothermal systems, Taupo Volcanic Zone, New Zealand". The work was supervised by Prof. Rickard and showed for the first time how U-series dating of calcite could be used to constrain the age of geothermal alteration (Grimes et al. 1998). Additional work using strontium isotopes as a tool to understand alteration styles within geothermal fields (Grimes et al. 2000) and a study of unique sulphur mounds at the Wiotapu geothermal system explained their process of formation (Grimes et al. 1999).

Jan. 1998 – Jan. 2000: NERC Post Doctorate Research Associate at Cardiff University. The title of the research was "Unlocking the early evolution of land plants and their biogeochemical impact through pyritisation of their remains", grant number GR3/11196. The research was concerned with pyrite formation pathways and the understanding of the process involved in the pyritisation of organic matter. This work involved collaboration between Prof. David Rickard (Cardiff University), Prof. Dianne Edwards (Cardiff University), Prof. John Parkes (Bristol University) and Prof. Derek Briggs (Bristol University). In its initial stage I designed and constructed a novel anoxic chemostatic reaction system for the investigation of pyrite formation pathways and pyritisation of organic matter under strictly controlled environmental and chemical conditions. Using this and other experimental systems I explain the environment and mechanism involved in the pyritisation of plant axes in the London Clay (Grimes et al. 2001a; Grimes et al. 2002a; Grimes et al. 2007). Conference presentations were made at the 9th (1999, Houston) and 10th (2000, Oxford) Annual V.M. Goldschmidt Conferences.

April 2000 – July 2003: NERC Post Doctorate Research Associate at Royal Holloway University of London (RHUL). The title of the research was "Greenhouse-icehouse transitions: testing the use of oxygen isotopes in associated mammal tooth phosphate and freshwater carbonates as an Eocene-Oligocene climate proxy", grant number GRE/12864. The work required me to design a new method for determining the d18OPO4 ratio in rodent tooth enamel so as to constrain the d18O of palaeo-freshwater (Lindars et al. 2001). I have also shown how the mean d18O of palaeo-freshwater can be combined with d18O values from other freshwater proxies (gastropod shells, fish otoliths, fish scales & charophyte gyrogonites) to calculate multiple terrestrial palaeotemperatures which, due to different mineralization times throughout the year, have differing climatic significance (Grimes et al. 2003). This work has culminated in the publication of the first multiple terrestrial palaeotemperature curve (Mean Growing Season Temperature, and Mean Warmest Growing Season Temperature) across the Eocene – Oligocene transition (Grimes et al. 2005). In addition, a paper outlining the application of this multi-palaeoproxy approach to the study of terrestrial climate change in the Quaternary has been published (Grimes et al. 2004b) and a related paper using carbon isotope results to infer the palaeodiet of rodents has also been published (Grimes et al. 2004a). My research techniques have also been used by the BBC program “Meet the Ancestors; Napoleon’s lost Army: The soldiers who fell” (screened on 3/2/2003) as a forensic tool to determine the birthplace of Napoleonic soldiers.
