Postdoctoral Fellow - X-ray Spectroscopy and Environmental Geochemistry
Eawag - Swiss Federal Institute of Aquatic Science and Technology
Microspectroscopic analyses on environmental samples can provide unique insights into molecular-level processes that control the fate and impact of trace elements in the environment. Such analyses however may be hampered by radiation-induced sample changes. Sample cooling offers a means to reduce such artifacts. In connection with ongoing research at Eawag and PSI on the environmental geochemistry of thallium, an environmentally highly relevant trace element, your two tasks are:
- Setup and installation of a cryostat system at the microXAS beamline at the Swiss Light Source that enables the microspectroscopic analysis of radiation- and redox-sensitive environmental samples;
- Perform micro-XRF/XAS/XRD studies on the microscale distribution and speciation of thallium and its association with various host phases in soils, sediments or rocks.
- You have a PhD degree in (environmental) geochemistry, mineralogy, chemistry, physics, material or environmental sciences;
- You are familiar with X-Ray absorption spectroscopy or other synchrotron based spectroscopic techniques and, ideally, their application in the field of environmental geochemistry. You are interested in environmental trace element geochemistry and in the further development, implementation and use of state-of-the-art synchrotron-based techniques for the elucidation of environmental processes;
- You enjoy working in an interdisciplinary research environment;
- Excellent communication skills in English are completing your application profile.
