København K
GEUS builds knowledge of the entire water cycle and contributes with high quality hydrogeological and hydrogeochemical knowledge in all subsurface and drinking water supply matters. With the purpose to strengthen GEUS’ competencies within the recovery of resources from water treatment residuals and circular solutions to ground- and drinking water related environmental problems, the Department of Geochemistry offers a 2-year position as postdoc with starting date 1. April 2022.
Job description
The postdoc will be part of the Department of Geochemistry and will work closely with a senior researcher on a project funded by the Independent Research Council of Denmark’s Green Transition call. The project broadly involves developing new technologies to detoxify and recover resources from the residual solid waste produced from drinking water treatment. Specifically, the project attempts to create a series of chemical and electrochemical methods to transform and valorise the arsenic-rich iron oxide precipitates generated as a by-product of removing arsenic, a potent carcinogen, from groundwater used as a drinking water source. Since groundwater arsenic contamination impacts millions of people in both high- and low-income regions, the developed resource recovery methods are expected to be relevant in a variety of geographic regions with different socioeconomic characteristics.
Based on the potentially wide range of methods that can be used to recover resources from this waste stream, a variety of expertise can contribute to this project. Therefore, qualified postdoc applicants can have diverse technical backgrounds, including environmental and chemical engineering, soil and surface chemistry, geochemistry, and materials science.
The postdoc is expected to contribute to several of the following functions related to the project’s key aims. In the application, please specify the functions you are most interested and able to contribute in and why:
Your qualifications
The appointment will be made on the basis of academic qualifications. The postdoc is expected to have several of the following qualifications:
Most importantly, we are searching for a highly talented, independent, motivated, and self-driven person who enjoys interfacing with researchers from different disciplines.
Department of Geochemistry
The aim of the Department of Geochemistry is to understand the fate of chemical substances in soil, groundwater and the deeper subsurface. The activities are characterised by both experimental work in the laboratory, field tests, and numerical modelling. The fate of pesticides and other xenobiotics in soil and groundwater is one of the department’s core research areas. Another research area includes the understanding of hydrogeochemical processes during CO2-rock interaction in soil, groundwater aquifers, water treatment facilities, and geothermal reservoirs. We also process groundwater chemistry data in relation to monitoring of the Danish groundwater. We are a staff of about 30 persons, comprising researchers, consultants, postdocs, technicians, and students.
We offer
Salary and conditions of employment
In accordance with the collective agreements between the Danish Ministry of Finance and the relevant eligible trade union. The appointment area is the Danish Ministry of Climate, Energy and Utilities and its institutions.
The Danish Ministry of Climate, Energy and Utilities considers diversity to be an asset and invites anybody interested, regardless of gender, age, religion, or ethnicity to apply for the position.
Further information
Please contact the Head of Department Claus Kjøller on tel. +45 51728202, e-mail: [email protected]. International applicants can read more about living and working in Denmark on GEUS’ homepage: http://eng.GEUS.dk/about/jobs/
Application
The application must include a letter of motivation, a CV, a list of publications with a separate indication of journal papers that are registered in ISI Web of Science, copies of any individual publications of particular relevance to the position and, if relevant, contact details of referees (max. 2). PhD diploma, as well as a summary of the PhD or other material that can document qualifications at postdoc level must be enclosed.
Submitted PhD theses that have not yet been defended may be sent with the application and will be included in the assessment. The PhD thesis must be approved by the University prior to appointment.
Please, send your application via GEUS’ homepage www.GEUS.dk under Jobs and Education (Job og Uddannelse). Your application must be with GEUS no later than 12.00 midday (Danish time), 15 February 2022.
Applications received after the deadline will not be considered.
The appointment procedure
An expert academic assessment committee consisting of two internal senior researchers will make an individual evaluation of applicants’ academic qualifications, where candidates are deemed qualified or non-qualified in relation to the position advertised. Then an appointments committee decide which of the qualified candidates they want to call for a job interview. The procedure is in accordance with “Circular on the appointment and assessment of academic staff at the Geological Survey of Denmark and Greenland”, Sections 4 and 7.

The postdoc is expected to contribute to several of the following functions related to the project’s key aims. In the application, please specify the functions you are most interested and able to contribute in and why:
- Design and execute laboratory and field (Denmark and South Asia) experiments with support from our technical staff.
- Perform experiments to separate arsenic from the solid matrix of iron oxide precipitates via chemical or electrochemical methods.
- Use biological, chemical, or electrochemical methods to transform residual arsenic into a less toxic and more stable form and to transform residual iron into magnetite.
- Characterize the pathways of the transformation reactions using synchrotron-based X-ray techniques (X-ray absorption spectroscopy, high-energy X-ray scattering).
- Lead the write up of experimental and field results in peer reviewed scientific journals.
Your qualifications
The appointment will be made on the basis of academic qualifications. The postdoc is expected to have several of the following qualifications:
- PhD degree in environmental engineering, nano-geochemistry, electrochemistry, materials science or similar field or equivalent qualifications.
- Solid laboratory experience. Previous field work experience or interest in developing field work expertise is a plus.
- Proficiency in electrochemical methods, with particular emphasis in the use of potentiostats for cyclic voltammetry and fixed potential measurements.
- Solid experience with synchrotron-based X-ray absorption spectroscopy and high-energy X-ray scattering methods to probe the structure and surface chemistry of nano-scale minerals. Previous experience in synchrotron proposal writing is a plus.
- Documented research qualifications, ability to work independently and to plan and carry out complicated tasks.
- Active part of the scientific community, i.e., willing to participate and organise conferences and workshops.
- Proficiency in English and academic writing.
