The role of metals is one of the many aspects investigated in a wide range of diseases and treatments. Synchrotron microprobes are powerful instruments in metal related research as they allow the spatial localisation of elements even at trace amounts therefore facilitating the investigation of changes in their levels or location as a product of disease or treatment. Further insights can be gained with x-ray absorption spectroscopy that can provide chemical information about the metal in question and its immediate environment. For examples of such work undertaken on I18 see "Collaborations".

Tina Geraki is Beamline Scientist on I18, the Microfocus Spectroscopy beamline. She joined Diamond in 2008 after positions at City University London, SRS Daresbury Laboratory and a short spell in industry. Her principal scientific interest is in the application of x-ray microprobe and absorption spectroscopy techniques in biomedical problems.
