In this talk I will present a review of the current understanding of the development of defect structure in the bulk and surface of rutile titanium dioxide and how they relate to departure from ideal stoichiometry. Titanium dioxide is the prototypical reducible transition metal oxide for academic study and has applications in self cleaning glass, odour reduction and photocatalysis. In our recent work we have related the electronic and geometric structure of the surface by scanning tunneling microscopy and photoemission spectroscopy to departure from stoichiometry and identified the key reaction pathways by which oxidation and reduction occur.
