Job Description
The Environmental Chemistry Group of Prof. Laurel ThomasArrigo is offering 1 PhD position in the Institute of Chemistry at the University of Neuchâtel (Switzerland). The research will be conducted within the SNSF Starting Grant ''MiMOC: Mineral-Mediated Organic Carbon dynamics in soils and sediments: Advancing understanding from the lab to the field''. The project involves 3 PhD students and 1 Postdoc.
Project description:
Iron mineral phases in soils play a key role in global element cycles. Yet our understanding of how fluctuating soil redox conditions affects mineral stability and transformation and impact the sequestration and/or mobilization of associated organic carbon is not clear. As part of a larger team, you will contribute to the development of novel approaches for investigating iron mineral transformations and the coupled fate of mineral-associated organic carbon in redox-dynamic soil and sediment environments. You will conduct laboratory and field studies on selected iron mineral transformation processes and their influence on carbon dynamics, using state-of-the-art experimental and analytical techniques including stable isotope tracers, synchrotron techniques, and XRD.
Main Duties And Responsibilities Include
* Design and execute laboratory experiments
* Publish research results in international scientific journals
* Attend and present research at national and international conferences
* Participate in teaching and supervision of laboratory practical courses
Your Profile
* MSc degree in a related field (e.g. environmental science, chemistry, mineralogy, ecology, soil science)
* Highly motivated to conduct scientific research in environmental biogeochemistry
* Good organizational and communication skills
* Knowledge in wet chemistry and lab techniques and a willingness to learn
* Experience with synchrotron techniques or XRD is an advantage
* Fluent English (written and spoken) is essential and basic French is an advantage
We Offer
* An inclusive and supportive working environment that encourages scientific curiosity
* Opportunities to further develop skills in advanced analytical methods (e.g., synchrotron XAS, XRD)
* Opportunities to attend and present at conferences and meetings
* The chance to build a scientific network in the fields of environmental and soil biogeochemistry
Start date :
Spring/Summer 2026
Duration :
4 years
