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.

  • Establishment of a CRISPR-Cas9 system for genome editing in L. salmonis and its application for the functional studies of genes involved in fertility and host selection.
  • 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:
