Joy is a postdoctoral researcher in the group. She completed her PhD at the University of Cambridge in the NanoPaleoMagnetism group lead by Prof. Richard Harrison, working on applications of FORC diagrams for environmental magnetism. Her current interests are in innovating environmental magnetism with focus on marine sedimentary records.

I am interested in how we can use magnetic minerals in sedimentary rocks to decode information about past environments. To do this, I use magnetic measurements and various experimental techniques to try and better understand how iron-bearing minerals are formed and preserved in time.
Currently my focus is exploring new magnetism-based paleoenvironmental proxies. I have been looking at marine sections in the South Atlantic and Pacific Oceans which experienced periods of abrupt environmental change, exploring links between sediment oxygenation and iron-bearing minerals.
