PhD fellowship in Nitrogen-cycle in Anoxic Groundwater Systems at Denmark Technical University

The overall aim of the PhD fellowship is to close the gaps in our knowledge on the anaerobic degradation pathways of nitrogen compounds in anoxic groundwater systems.

Scientific focus of the announced PhD position
Elevated inorganic nitrate concentrations in aquatic environments can cause significant impacts on aquatic ecosystems and human health. Nitrate concentrations in groundwater have increased over the past decades due to increased agricultural activity that is directly linked to food production. In addition many other sources such as municipal wastewater can also contribute to nitrate contamination in groundwater and surface water. To assess the chemical history of nitrogen-compounds in groundwater, stable isotope technique has proven to be a powerful tool in environmental science.

The research questions will primarily be investigated using microcosm experiments linked to field investigations. The project will analyze the dominant sources and sinks of nitrogen in groundwater and their degradation pathways using stable isotope technique.

Qualifications
At the date of appointment candidates must hold an MSc degree in natural science (e.g. bio/geochemistry, microbiology, hydrology), preferably with a strong background in biogeochemistry in hydrogeological or marine systems. The successful candidate must be an efficient team worker, have good communication skills, and have a critical approach to formulation and testing of hypotheses. Practical experience and a wish to work in the field and in the lab is a prerequisite.

The scholarship is open to both Danish and international applicants.

Scholarship Application Deadline: 31 January 2011
