Joël obtained his PhD at the University of Basel, Switzerland in 1996 for work on the geochemistry and mineralogy of metamorphosed syn-genetic exhalative Mn deposits. After a post-doctoral position at Monash University, he joined the South Australian Museum and the University of Adelaide in 2002.

 

Position at Other Organisation

  • Lecturer, School of Earth and Environmental Sciences, The University of Adelaide

 

Research Interests              

Joël established the Minerals, Microbes & Solutions research group, dedicated to using state-of-the-art experimental techniques to study the transport and deposition of metals and mineral-microbe-fluid interaction in geological environments. Joël has a strong interest in the application of physical sciences to Earth Sciences. He also conducts active research in descriptive mineralogy, and in uranium and REE geochemistry.

 

Current Research Projects 

Deep and smelly: exploring the roles of pressure and sulphur in hydrothermal metal transport.  J. Brugger, D. Testemale, D. Sherman.  2013–2015, Australian Research Council Discovery project, $340,000.

Hot (100–600 ˚C), salty fluids carry metals deep in the Earth’s crust. These fluids are responsible for the formation of Australia’s mineral wealth. We will combine state-of-the-art in-situ spectroscopic techniques with recent advances in first-principle molecular dynamic simulations to study the roles of pressure and sulphur on the transport of metals in the upper and middle crust (≤50 km) at the molecular level. We will test the hypothesis that different regimes in metal transport exist in shallow (<4 km) an deep (>10 km) hydrothermal systems. This understanding will enable to improve reactive transport modeling under “extreme conditions” for metals such as Au, Cu, Pb, Ni, and Co.
