Biostatistics

The research group focuses on applied statistics within plant phenotyping, agronomy, and ecotoxicology.

Trends data with floating drone

We work closely with Nordic plant breeders on developing and accessing tools and methodology for plant phenotyping using drone data. We develop and optimize designs for agronomic experiments and evaluate the reproducibility of data obtained from different sources and or under different conditions. Part of our work consist in developing R-packages for easier accessibility for the end-user.  

 

  • Benchmark dose methodology
  • Dose-response models
  • Plant phenotyping
  • Design of experiment
  • Linear mixed models
  • Simultaneous inference

The aim is to advance, extend and enhance statistical methodology specifically within toxicophenomics with the aim of optimizing the use of high-throughput plant phenotyping in advanced environmental toxicological risk assessment. Also, the aim is to extend the research group with more data science experience towards an increased utilization of deep learning, e.g., neural networks, for image processing for trait recognition and/or plant organ counting.
