PhD Student

to work on the fundamental understanding of the coupled adsorption and electron transfer interface reactions governing the retention of redox-sensitive radionuclides by Fe(II)/Fe(III) bearing clay minerals within the European Joint Program EURAD

Your tasks

You will investigate the interaction between redox-sensitive radionuclides (e.g., U, Tc, or Se), and purified Fe(II)/(III)-containing clay minerals by combining different approaches: (i) adsorption experiments with radionuclides under different relevant geochemical conditions, (ii) molecular scale speciation using X-Ray absorption spectroscopy and (iii) adsorption modelling. The aim is to correlate mineral properties with respect to its redox reactive iron content to the degree of radionuclides retention and molecular scale surface speciation. To accomplish this work you will have to carry out experiments in a radiochemical A-type laboratory, to perform X-Ray absorption spectroscopic measurements at the Rossendorf Beamline (ROBL) located at the European Synchrotron Radiation Facility (ESRF) in Grenoble (France) and to evaluate and model your data. Your working location will be at PSI, however, you will travel frequently to the project partners at ROBL in Grenoble and BRGM in Orleans (France). You will communicate your scientific results in peer-reviewed journals, workshops and conferences.

Your profile

You are a highly-motivated individual with good communication skills in English and easily adaptable to different working environments. You hold a Master degree/Diploma in chemistry, earth or environmental sciences or related field. Welcome assets include experience in the handling of radionuclides, in electrochemistry or in synchrotron based X-Ray absorption spectroscopy.

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.
