Responsibilities and tasks

Research focus will be within water quality in aquaculture systems, primarily recirculating aquaculture systems (RAS). In particular, effects of components and water disinfection on water quality and biofilm will be investigated. Responsibilities and tasks will include:

  • Design and performance of controlled experiments in batch and pilot scale systems investigating effects of disinfection (i.e. hydrogen peroxide, peracetic acid, ozone, UV) on water quality.
  • Research and test of methods and technologies to monitor, quantify, and assess chemical and microbial water quality parameters.
  • Modify and develop assays to quantify bacterial activity in water and in biofilm.
  • Participate in/perform water quality studies on commercial aquaculture facilities.
  • Scientific dissemination of results and participation in grant proposals.

We expect the candidate to have practical experience and theoretical understanding of general water chemistry as well as of chemical and microbial processes related to aquaculture. The candidate is expected to have experience with designing and conducting experiments in the lab, and to be open-minded for field trials and applied research in collaboration with the aquaculture industry. Expertise on characterization of water quality and biofilm processes and knowledge of recirculating aquaculture technology including treatment processes will be an asset.

The candidate must have:

  • A PhD degree (or equivalent qualifications)
  • Knowledge about water treatment processes
  • Practical and solid theoretical understanding of water chemistry and/or microbiology
  • Lab skills and experience with chemical and microbial analysis
