Summary

After spending 13 years as a 'hands on' curator, specialising in the mineralogy, gems and hard rock geology aspects of the collection, the last 5 years have been spent in a role with increased management responsibilities, and I lead the team of curators, post docs and volunteers in the mineral and planetary sciences division, covering meteorites, minerals, gems, terrestrial analogues, hazardous geological materials and historic apparatus.

My curation duties focus on the on going development of the mineral collection, both in terms of new objects and the new data/research on all objects. I have recently become heavily involved in the planning and building of bespoke curation facilities with specifically defined processes, policy and protocol for niche areas of geological collections. I continue to perform research on the mineral collection, with a focus on the identification and characterisation of new, 'unknown', novel and unusual naturally occurring mineral phases.

As a consequence I have a deep understanding of the systematic mineralogical nomenclature, new minerals and have published extensively on these subject areas.

Where possible I have focused this research on minerals from the UK, where topographic mineralogy and geodiversity is particularly interesting.

I am interested in the applications of mineral sciences across both the scientific and heritage sectors and how collections can be built within (and outside) museums to maximise the relevance of mineral sciences and communicate this to the public.

I have extensive experience of a number of Optical, Electron Beam and Diffraction techniques all essential in the characterisation and identification of mineral phases and am highly competent at speaking to the public. For more information on my analytical expertise please contact me directly.
