DESCRIPTION:*Emma McCabe\, School of Physical Sciences\, University of Ken
 t*\n_Insights into long-range and local phenomena from complementary techn
 iques_\n\nUnderstanding structure – property relationships is essential 
 for explaining the origins of physical phenomena. The structural informati
 on we gain from long range diffraction methods (such as X-ray and neutron 
 powder diffraction)\, particularly if collected across a phase transition 
 or as a function of temperature or field\, is invaluable. However\, these 
 data are often not sufficient to give us the whole picture\, and complemen
 tary techniques (including more local probes as well as insights from theo
 ry) can help give a deeper understanding of materials.\nI’d like to pres
 ent work on a range of materials including polar oxides [1\,2] and magneti
 c oxychalcogenides [3] based on our results from diffraction\, property me
 asurements\, muon spin rotation and density functional theory calculations

 s\, University of Cambridge*\n_Quantum Criticality in Multiferroic Systems
 _\nMy research is currently focused on the tuning of quantum criticality i
 n charge ordered systems. I am particularly interested in the behaviour of
  quantum critical points in systems having more than one coupled order par
 ameter such as multiferroic materials. I carry out electric and magnetic m
 easurements at cryogenic temperatures whilst using pressure as a tuning pa
 rameter\, involving the use of piston-cylinder and diamond anvil pressure 
 cells.
