Doctoral researcher (m/f/x)
Subject: Aerobic transformation and effects of antibiotics on microbial function and ecology
Project start: 1st April 2020. Working time 65% (25.35 hours per week), limited to 3 years.Your tasks:
Contamination of water ecosystems with antibiotics is of high concern since it may contribute to the prevalence of antibiotic resistance. A novel dimension of antibiotic contamination is its impact on the functioning of natural ecosystems. The doctoral researcher will study i) the transformation mechanisms (biological and photo chemical) of antibiotics in surface waters and ii) the effect of antibiotics on microbial function, e.g. metabolic activity and ecology of natural microbial communities The tasks of the candidate will include the use of 1) stable isotope fractionation and labelling to identify transformation mechanisms and quantify the microbial activity 2) molecular biology techniques (16S rDNA amplicon sequencing, qPCR) to analyse microbial community structure and the abundance and spread of antibiotic resistance genes, and 3) single cell approaches (FISH coupled to nanoSIMS) to link microbial activity to cell’s phylogenetic identity. Experimental work includes field sampling, microcosm- and lab scale set-ups.Your profile:
The candidate should have a master’s degree in Environmental Science, Biology, Environmental Biotechnology, Biochemistry or equivalent fields; ideally with a strong interest and profound background in microbiology and molecular biology. Knowledge of microbial ecology techniques e.g. FISH, stable isotope probing is important.The candidate should be proficient in English and motivated to work in an international and interdisciplinary team.
We offer:
- Top level interdisciplinary research at a research centre which enjoys an excellent reputation within Germany as well as internationally
- Excellent technical facilities
- Work in inter-disciplinary and multinational teams
- Excellent links to national and international research networks
- Support and optimal training courses by our graduate school (HIGRADE)
