Doctoral researcher (m/f/d)


  • Master's degree in Environmental Science, Biology, Environmental Biotechnology, Biochemistry or equivalent fields
  • Strong interest and profound background in microbiology and molecular biology
  • Knowledge of microbial ecology techniques e.g. FISH, stable isotope probing is important

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 photochemical) 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) singlecell approaches (FISH coupled to nanoSIMS) to link microbial activity to cell's phylogenetic identity. Experimental work includes field sampling, microcosm- and labscale set-ups.
