The postdoctoral researcher will be part of the CLEAR group. The project is funded by the European Research Council (\u201cGlass2Melt: Universal Model of the Density of Deep Silicate Melts\u201d).\u00a0 \n
Within the research group CLEAR, we endeavour 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 would want to be part of a five-year research program to quantify the density of silicate glasses and melts at high-pressure conditions. The primary research focus will be on measuring the thermoelastic response (e.g., the thermal expansion coefficient) of silicate glasses and melts in the resistive- and laser-heated diamond anvil cell using supercontinuum-based interferometry and other optical techniques. The resulting data will quantify the effect of temperature on the volume of multicomponent silicate glasses across the pressure range of the Earth\u2019s mantle, and contribute to the foundation of the universal silicate melt density model. \n
The successful candidate will further develop the all-optical method for density measurements in the diamond anvil cell, and collaborate with the existing group members as well as with Prof. Dr. Bjoern Winkler (Goethe University Frankfurt), Dr. Ilya Veksler (GFZ), and Dr. Sergio Speziale (GFZ) to gain deep insights into the composition-structure-property relation in the silicate glass system. \n
