Marie Saitou Lab

Faculty of Biosciences · Norwegian University of Life Sciences (NMBU)

How do genomes enable organisms to evolve, adapt, and persist?

  • How new traits and regulatory systems arise, and how structural variation, chromosome evolution, and whole-genome duplication reshape genomes.
  • How wild organisms thrive in their environments, where populations become vulnerable, and how genomic evidence can inform ecology and conservation.
  • How domestication, human-driven selection, and infectious disease influence molecular adaptation.

We address these questions using population and comparative genomics, transcriptomics, gene-regulatory analysis, and evolutionary modelling.

Seminars and scientific exchange are welcome. Marie is happy to give talks at other institutions, and we welcome enquiries from researchers interested in visiting or speaking at NMBU.

Lab news

October 2026SeminarNew!

Joint seminar by BIOVIT (NMBU) and the Norwegian Veterinary Institute

Marie Saitou (BIOVIT, NMBU) is organizing a joint seminar with the Norwegian Veterinary Institute. Marie Saitou and Arturo Vera Ponce de León (BIOVIT, NMBU) will discuss human evolution and the Atlantic salmon gut microbiome, while Wasimuddin and Johanna Hol Fosse (Norwegian Veterinary Institute) will present research on microbiome dynamics and host–pathogen interactions in infectious salmon anaemia.

September 2026SeminarNew!

Marie gave a talk entitled ‘The Human Species as an Outcome of Evolution: From Growth, Population Genomics, and Lactation’ at the Norwegian Institute of Public Health (FHI).

The seminar was hosted by Yunsung Lee.

September 2026GeneralNew!
