UK: PhD Position Biogeochemistry and Control of Biological Nitrous Oxide Production Technical University of Denmark

Font size: Decrease font Enlarge font

The Department of Environmental Engineering at the Technical University of Denmark (DTU) invites applications for one PhD and one postdoctoral fellowship position to help unravel the environmental and biochemical mechanisms and controls of N2O dynamics during biological wastewater treatment. Laughing gas (N2O) is a greenhouse gas 300 times stronger than CO2 and a dominant ozone destroying chemical. Biological processes – the same that are essential for removing polluting reactive nitrogen from wastewaters – are potential sources of N2O.

Responsibilities and tasks
The topic of the PhD position is, in collaboration with others, (1) to use mathematical modeling to identify targeted experiments with the aim to track and quantify the mechanisms of N2O transformation in N cycling communities, and (2) to conduct experiments using 15N and 18O stable isotope enrichments and mass spectrometry in combination with novel on-line sensor technologies at lab-scale and pilot-scale. Emphasis will also be on the quantitative evaluation of rate-controlling parameters on N2O dynamics.

The team will focus on synthetic and open microbial communities that can be found in various biological nutrient removal processes, with a special interest in those performing autotrophic N removal.

For further information on the project, visit the preliminary homepage (N2OMan).

Qualifications
The successful applicant for the PhD position will have a strong training and interest in one or more of the following fields: Biogeochemistry, Environmental Biochemistry, Microbial Ecology, Bioreactor/Bioprocess Technology, Inorganic Chemistry, with evidence of experience in the use of stable isotopes, bioreactor operation, or microsensor application. The candidate will have a high motivation for research, evidence of solid written and oral communication skills, and enjoys working in an international and cross-discplinary team. At the time of appointment, the candidate should have M.Sc. degree in Environmental Sciences, Biology, Microbial Ecology, Biochemical, or Chemical Engineering or related discipline.

Assessment
The assessment of the applicants will be made by an assessment committee chaired by Prof. Barth F Smets.

Application procedure
Your online application must be submitted no later than 15 January 2014.
