PhD candidate (f_m_x) Research on Properties of carbonate glasses at high pressure
Reference Number 7788
The project "Densities, structures and refractive indices of carbonate glasses at high pressure" is funded by the Deutsche Forschungsgemeinschaft. The dissertation will be submitted at the University of Potsdam.
Within the research group CLEAR we endeavor to understand large scale geological processes that operate deep inside planets. Our approach is to recreate high pressure-temperature conditions in the laboratory and examine various physical properties of geomaterials (minerals, rocks, glasses, and melts) in situ using state-of-the-art spectroscopic techniques. We then use these properties in collaboration with geodynamicists to create numerical models of planets.
We are looking for a highly motivated individual who wants to earn a PhD in geosciences and is interested in developing an expertise in spectroscopic measurements in a high-pressure device known as the diamond anvil cell. The primary research focus will be on the refractive index and density of carbonate glasses at high pressure with implications to the properties of carbonate melts in the Earth’s mantle. The successful candidate will also take active part in the ongoing research collaboration with the group of Prof. Björn Winkler (Goethe University Frankfurt/Main) to gain insights into the structure-property relation in carbonate glasses/melts at high pressure.
