Research Expertise -
 I have been working in the field of X-ray absorption spectroscopy for more than 25 years. I mainly work in areas that could have the word geochemical in their title, but have interests in other fields as well.
Current Projects
I am currently involved in many projects using X-ray absorption spectroscopy, notably:
  • with University College London (and RC@H), in developing in situ micro-imaging techniques for single catalyst particles,
  • with the NERC-funded consortium Lo-Rise aimed at defining the key physical, chemical and biological processes which govern radionuclide transport, both in the soil/sediment solution phase, and transfers to biota,
  • With the NERC-funded NHM-led  COG3 consortium looking at Co mineralogy and extraction
  • with the University of Manchester in a NERC funded project looking at the fate of Uranium particles.
  • with medical professionals from The National Orthopaedic Hospital, Stanmore looking at the fate of metal atoms in the tissue around artificial hips,
  • with the Mary Rose Trust and the University of Kent in developing technologies to help preserve historical artefacts in particular archaological timber,
  • with the University of Manchester in developing containment cells to study higher activity radionuclides with XAS at Diamond.*
  • with the University of Leeds in studying Molybdenum in deep water sediments
  • with the University of Aston looking at metals in tissue

*This project involves a student sponsored by the STFC Futures programme.

Biography - +


Fred Mosselmans is Principal Beamline Scientist on the Microfocus Spectroscopy beamline I18, and a visiting professor at the University of Manchester, School of Earth and Environmental Sciences and a visiting lecturer at the University of Oxford. His main scientific interests lie in the development and application of X-ray Absorption Spectroscopy, particularly with regard to Environmental Science research. He is currently serving on a beamtime review panel at the Swiss Light Source.

He regularly teaches courses on the analysis of XAFS data and gives part of a module at the University of Kent.

Fred did his first degree at Cambridge University and then a PhD at Southampton working for John Evans.  He undertook post-doctoral work at Southampton and then Manchester before joining the SRS Daresbury Laboratory where he worked as a beamline scientist for 11 years before joining Diamond.
