Background and activities

Lepeophtheirus salmonis (sea lice/lakselus) infestation in farmed salmon inflicts a huge economic loss in the Norwegian aquaculture industry. My Ph.D. research intends to assess the clues to control the sea lice infestation by understanding the underlying genetic mechanisms.

  • Functional studies of genes involved in metabolic pathways.
  • Identification of genomic markers to track and categorize sea lice.

My PhD is a part of Taskforce Salmon lice, cooperation between NTNU and the aquaculture industries in Mid Norway with collaboration among multiple research institutions. For more information you can visit the link below:
