PhD Scholar in Environmental Chemistry (3 years)
GEUS builds knowledge of the entire water cycle and contributes to a future-proof water resource management in Denmark. The Geochemical Department at the Geological Survey of Denmark and Greenland (GEUS) seeks applicants with an environmental chemistry background for a three-year PhD position who will be registered at the University of Copenhagen targeting the fate of organic micropollutants in soil and groundwater.
About the position
This job is part of a broad research programme funded by the Novo Nordisk Foundation, which shall study how the redox-active function of biochar impacts the generation of Reactive Oxygen Species and organic carbon, and resulting changes in transport, transformation, and persistence of inorganic and organic contaminants in Danish groundwaters.
The project integrates molecular-to-macroscale laboratory experiments (column, microcosm), successive extraction/leaching schemes and advanced analytical techniques. By linking redox chemistry and contaminant fate, the project will provide new insights into how biochar applications influence both climate mitigation goals and groundwater protection.Ultimately, this research will deliver the fundamental knowledge needed to ensure that large-scale biochar deployment contributes not only to carbon removal but also to the long-term safety and sustainability of Denmark’s groundwater resources.
Who are you?
You have a master’s degree in environmental science, or a closely related field. A solid background in contaminant fate, redox chemistry, or soil and groundwater processes will be highly valued.
We emphasise that you have hands-on experience with laboratory-based experimental work, such as batch or column experiments, and a strong interest in understanding the transformation and transport of contaminants in complex environmental systems.Experience with analytical techniques for organic and/or inorganic contaminants (e.g., chromatography, spectroscopy) is considered an advantage.
We imagine that you are curious, motivated, and capable of working both independently and as part of an interdisciplinary research team. You have strong analytical thinking skills and a structured approach to problem-solving, combined with creativity and scientific curiosity.You are comfortable working at the interface of chemistry, environmental science, and geoscience.
You must be able to communicate in English, and since the primary language of the organisation is Danish, you should be prepared to learn Danish.
Meet your new colleagues
You will become part of the Department of Geochemistry. The department researches the fate of chemical substances in the entire water cycle, but with a particular focus on soil, groundwater and drinking water as well as the deeper underground.The activities are characterized by a high degree of experimental work in the form of laboratory and field trials, which are often supplemented with numerical models.
Our research includes naturally occurring substances as well as microbiology, pesticides and other harmful substances, and we have as a common denominator that we would like to create knowledge that can contribute to a better environment for future generations.
We are broadly based professionally with, among others, engineers, geologists, environmental chemists and microbiologists, all of whom work with groundwater-related data e.g., in relation to the national groundwater monitoring as well as to understand geochemical processes in the subsoil This could be in connection with CO2 storage, pollution with environmental contaminants, nitrate in groundwater and surface water, etc.We are approx. 40 employees divided into administrative staff, technicians and researchers at different stages of their careers.
A working environment with a focus on professional development and well-being
There are many good reasons why you should choose a working life at GEUS.
We are a diverse staff of about 300 committed employees. Trust and flexibility are keywords. The working environment is lively, informal and international. Our tasks are versatile and there are plenty of opportunities for you to influence the development of your task portfolio.
We prioritise professional development, among other things by offering access to courses and other relevant activities. Socialising is also very important at GEUS, and we have a rich social life with a staff club, an art association and more.
At GEUS, we prioritise the well-being of every single employee. We prioritise that the Heads of Departments are close to the employees, and we have flexible working hours that allow you to organise your life so that there is time for what matters to you.If you need to work from home occasionally, that is also possible.
Furthermore, we have a gym with associated physiotherapists.
Salary and terms of employment
