Ecosystems are impacted worldwide by global change processes such as global warming and habitat destruction, but many of the effects probably go unnoticed. High throughput sequencing (HTS) of environmental DNA (eDNA) can be used in a cost-effective and non-destructive way to monitor and understand how ecosystems, and biodiversity therein, are affected. eDNA based biomonitoring will also unveil undescribed life-forms, and may be the only feasible way to start closing the knowledge gap on Earth’s biodiversity. Massive amounts of data for downstream computational analyses are generated by the HTS analyses. We welcome proposals from candidates with a strong background in bioinformatics, statistical modeling and data science in order to: (i) develop improved bioinformatics methods for analyses of eDNA sequence data, (ii) develop and streamline statistical models and computational methods for monitoring ecosystem change through eDNA, and (iii) apply relevant computational methods to address specific cases related to global change ecosystem effects.

  • Hierarchical sampling designs and statistical modelling for biodiversity studies/monitoring by use of eDNA
  • Develop and implement machine learning and artificial intelligence for data analyses
  • Coupling of massive eDNA datasets
  • Upscaling of eDNA biomonitoring
  • Robust workflows for eDNA biomonitoring
