Hi,

my name is Arne Jacobs and I am an evolutionary biologist with interests in rapidIMG_0327 evolution, population genetics, adaptation genomics and gene regulatory evolution in natural systems, as well as developmental and morphological evolution, particularly in fishes. I am currently a Postdoc in the lab of Nina O. Therkildsen in the Department of Natural Resources at Cornell University.

My research focuses on integrating eco-morphological, functional genomic and population genomic approaches to understand rapid & parallel phenotypic adaptation. In the Therkildsen Lab, I am working on the genomic mechanisms of local adaptation under gene flow in the Atlantic silverside, a small estuarine fish that is distributed along a steep climatic gradient along the North American Atlantic coast. Previously, I focused on the extraordinary diversifications of salmonid fishes in postglacial lakes. Therein, I focused on studying extensive replicated diversifications in one of the most diverse vertebrate species, Arctic charr (Salvelinus alpinus); examining ecological, phenotypic and genomic patterns and processes of contemporary trophic divergences in European whitefish (Coregonus lavaretus); and genomic patterns of life history evolution in the enigmatic ferox trout, a brown trout (Salmo trutta) ecotype.

I also have a great interest in understanding the genomic architecture underlying complex traits and gene regulatory evolution across different evolutionary scales and under different demographic scenarios.

If you want to find out more about my past and ongoing research have a look at my research page and my publications.
