Huge congratulations to Joy on passing her viva. Her fantastic (award winning) work on the development of FORC diagrams as a tool for unmixing rock magnetic signals was suitably celebrated with a giant ‘FORC’ cake. Joy’s thesis has shed new light on the role Fe reduction plays in controlling the magnetic properties of sediments, and lead to the discovery of a new type of magnetite – trabecular magnetite – that has an internal nano-porous structure resembling that of trabecular bone. Joy will now be heading off to Peking University to work with Liao Chang. So long Joy, and thanks for all the FORCs!
