María-Eugenia López

Maria Lopez
I am a postdoc at SLU Aqua, interested in the molecular mechanisms that organisms use to cope with and adapt to their environments. My research focuses on population genetic analyses of genomic data, particularly on detecting natural/artificial selection, describing population genetic variation, and association mapping.
