Apart from antibiotic resistance, I am also more generally interested in how, for example, chemicals can perturb microbial ecosystems, how that affects ecosystem services, and how bacteria evolve to cope with pollutant load. To this end, I have studied the distribution of detoxification systems in marine environments, and how pharmaceutical pollution have affected lake sediment communities. I have also contributed to a report on novel techniques to assess toxicant effects in aquatic environments, and studied periphyton communities (often used in toxicity testing) through metagenomics.

Open questions of interest

  1. How can we link perturbation of a microbial community to genetic changes?
  2. How large disturbances are needed to cause certain degrees of effects on microbial species loss, loss of key ecosystem functionality, and/or loss of ecosystem services?
  3. How do dormant species and the “rare biosphere” contribute to the stability of microbial communities?
  4. What is the role of mobile DNA in resilience of microbial ecosystems to perturbations?
  5. In which circumstances can evolutionary rescue play a role in mitigating disturbances on microbial communities?
