Eawag Switzerland Deptt of Water Resources and Drinking Water PhD Scholarships on Environmental Soil Chemistry 2025.
Fully Funded PhD Scholarships on environmental soil chemistry | Eawag
Deadline: 30 June 2025
The Department Water Resources and Drinking Water at Eawag invites applications for 2 PhD student positions in environmental soll chemistry (m/f/d)
1. About the project:
The two 4-year PhD student positions are part of a project funded by the Swiss National Science Foundation (SNSF). This project involves 2 PhD students and 1 postdoctoral researcher working together with scientists at Eawag and ETH Zurich. The aim is to assess trace element dynamics in periodically waterlogged soils under current and future climatic conditions.
One PhD project will focus on Tl and As in naturally TI- or As-rich soils, the other on Cu, Pb and Cd in anthropogenically contaminated calcareous soils. In a first part, both projects will address how seasonal variations in temperature and other factors affect rates and extents of soil reduction and trace element mobilization into pore water upon flooding. This includes an exploratory part on links to microbial community structure.
In a second part, one PhD student will focus on Identifying and quantifying the mechanisms of Tl release and the factors governing As release from waterlogged soils. The other PhD student will focus on coupled Cu, Cd and Pb dynamics under sulfate-reducing conditions, namely the competitive formation of poorly soluble metal sulfides and the mobility of metal sulfide colloids in soils.
Both PhD projects involve extensive field sampling, laboratory microcosm studies, and the use of state-of-the-art (e.g., ICP-MS, XRF) and advanced techniques (e.g., XAS, STEM) for the analysis of water, colloid and soil samples. For synchrotron X-ray analyses, the PhD students will collaborate with the postdoctoral researcher.
II. Tasks & Responsibilities
Two motivated PhD students are needed to work on the following tasks:
Organize and perform regular field sampling campaigns in Switzerland.
Design and carry out demanding laboratory experiments and biogeochemical analyses.
Perform synchrotron X-ray analyses for trace element speciation in soils.
Explore and quantify trace element release mechanisms and controlling factors.
Within the framework of the project, you will have opportunities to investigate your own creative ideas and to closely collaborate with each other as well as with other partners at Eawag, ETH Zurich and other institutions.
An essential part of your work will consist of writing up your results for publication in peer-reviewed journals and communicating your findings to partners and at international conferences. Furthermore, it is expected that you manage regular project meetings and that you take part in some teaching activities at ETH Zurich.
