my name is Arne Jacobs and I am an evolutionary biologist with interests in rapid evolution, adaptation genomics and gene regulatory evolution in natural systems, 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  better understand the proximate and ultimate mechanisms underlying rapid adaptation and phenotypic evolution. I also have great interest in understanding the developmental and molecular mechanisms underlying adaptive phenotypic changes. I think that integrating these diverse approaches will allow one to gain a more complete understanding of how the fascinating biodiversity surrounding us has evolved. Ultimately, this knowledge will be key to preserving and protecting this diversity. To do so, I am focusing my work on a range of systems, ranging from local adaptation to steep thermal clines in Atlantic silversides, adaptation to urban environments in great tits, rapid re-evolution of European whitefish diversity after eutrophication, and parallel ecotype evolution in Arctic charr.

In the end, it is extremely exiting to study the natural history of the species we share this planet with and a huge privilege to gain a glimpse into the evolution of this extraordinary biodiversity.
