David Ray is an experienced teacher, geologist, academic and manager, having worked in the education sector and energy industry. His research interests are focused upon sequence stratigraphy, the drivers of sea-level change, and event stratigraphy; most notably within the Silurian and Cretaceous.


  • BSc Geology with Palaeontology. Imperial College, London, UK.
  • PhD. University of Cincinnati, Department of Geology, Ohio, USA.
  • Advanced Certificate in Education. Canterbury Christ Church University, Kent, UK.

Postgraduate supervision

David Ray has supervised postgraduate projects focused upon the Silurian. His research interests are in the following areas:

  • The identification and correlation of sea-level changes (sequence stratigraphy)
  • Stable carbon isotope stratigraphy
  • Correlation of event beds (e.g., volcanic ash bands and biotic mass occurrences)
