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 the NERC-funded NHM-led  COG3 consortium looking at Co mineralogy and extraction
  • with medical professionals from The National Orthopaedic Hospital, Stanmore looking at the fate of metal atoms in the tissue around artificial hips,
  • 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 involved a student sponsored by the STFC Futures programme.

Biography - +


Fred Mosselmans is Principal Beamline Scientist on the Versatile XAS beamline I20,  and a visiting professor at the University of Manchester, School of Earth and Environmental Sciences. His main scientific interests lie in the development and application of X-ray Absorption Spectroscopy, particularly with regard to Environmental Science research including the behaviour of radionuclides.

He regularly teaches courses on the analysis of XAFS data.

Fred did his first degree at the University of Cambridge 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, where he was Principal Beamline Scientist on the microfocus spectroscopy beamline I18 for 12 years before moving to the I20 beamline in 2018. He has over 180 scientific publications.
