Honorary Research Fellow , University of Bristol

I have an academic background in geology and geochemistry and worked in the exporation side of the oil industry. 

My interests now lie in the history of geology. 

I recently published a popular science book on the history of dating the age of the Earth entitled: 'The Dating Game: One Man's Search for the Age of the Earth'. 

I have also written a book on the medical and geological work of James Parkinson (1755-1824) who gave his name to Parkinson's Disease, and started to research the geological work of David Mushet (1772-1847) who, although famous for his experiments on the manufacture of iron and steel, is not know for his geological expertise,
