My research

I am interested in how heritable traits work and in finding causative genes, sequence variants and molecular pathways for quantitative traits. My current project deals with domestication traits of the chicken, and I use genetic mapping combined with genetical genomics to hunt down the interesting genes.

Here are some blog posts about my work:

Paper: ”Mixed ancestry and admixture in Kauai’s feral chickens: invasion of domestic genes into ancient Red Junglefowl reservoirs”

From my halftime seminar

Paper: ”Heritable genome-wide variation of gene expression and promoter methylation between wild and domesticated chickens”
