Key details

Professor David S Wray

Deputy Faculty Director – Research & Enterprise (Science)


Professor Dave Wray is the Director of Research and Enterprise within the School of Science; he is also a Professor in Applied Analytical Chemistry. He is the founder and Technical Manager of the ISO 17025 accredited Analytical Services Laboratory housed within the School. He specialises in inorganic elemental, isotopic and mineral analysis by ICP- and X-ray-based techniques for the purpose of solving geochemical, forensic and environmental challenges.

Much of his published work focuses on the use of elemental and mineral data in recent and geological successions to better understand palaeoenvironments and anthropogenic pollution. His laboratory supplies chemical and mineralogical data to the petroleum industry to facilitate sub-surface correlation in petroleum reservoirs and source rocks.

Since the year 2000 his team has delivered results from over 120,000 samples to a range of clients based in Europe, the USA and Australia; this equates to about 5 million individual pieces of data. In 2007 he was awarded the University of Greenwich Research and Enterprise award in recognition of his work; he has also been awarded the Richardson Award by the Geologists' Association in recognition of the best paper published in the journal Proceedings of the Geologists' Association in 2006.

Professor Wray attained a BSc Hons Geology degree at the University of Sheffield before moving to the City of London Polytechnic to undertake a PhD. He was appointed as a Lecturer in Applied Geochemistry at the University of Greenwich and subsequently become a Reader in Applied Analytical Chemistry. He currently holds the post of Director of Research and Enterprise (Enterprise) within the School and is a member of the School Management Team.

Researcher ID profile

Consultancy

Key funded projects

  • Analytical Services Laboratory. This raises ca. £250,000–£500,000 p.a. through commercial funding from external clients, principally the oil industry, forensic and environmental consultants. Where appropriate, this work also results in scientific publications within refereed journals. The total revenue for this activity is in excess of £3million. The Unit is accredited to ISO 17025 by UKAS.
  • Knowledge Transfer Partnership (KTP) 2012-2014. Analytical and interpretative protocols for heavy mineral spectroscopy to establish an automated provenance service for petroleum reservoir correlation and mapping. £100,000.
  • Contribution to PhD studentship from Chemostrat Ltd 2012-2015. £25,000.
  • Contribution to PhD studentship from Chevron 2013-2015 $45,000.
  • EU Life grant £227,000 'Cliffe Marshes conservation park' (Consortium bid lead by Medway Council, total bid value £860,000; monies eventually returned to the EU due to legal issues relating to land ownership).
  • EU Interreg grant: £228,000 'Pilot study of technology transfer in water purification'. (With P Carey, Greenwich and L Boyle, U. Kent).
