After graduating with a PhD in condensed matter physics from the University of Western Australia in 1998 and undertaking a three-year postdoctoral position at the Tokyo Institute of Technology (1998–2000), Barbara moved to Adelaide in 2000 to take up a postdoctoral position with Allan Pring in Mineralogy at the Museum.  Subsequently, she has oscillated between employment at the South Australian Museum, CSIRO and the University of Adelaide.  Barbara has spent most of the time based at the Museum working with Allan Pring and Joel Brugger studying the formation of ore deposits and mineral replacement reactions.

 

Position at Other Organisation

Affiliate with Chemical Engineering, University of Adelaide

 

Research Interests

The relationship between the atomic structure and properties of materials and their applications to Earth Sciences.

 

Current Research Projects
