Karlsson Lab

We use evolution to explore how genetics affects health. We study everything from cholera to dog behavior to mammalian evolution to understand how genes work, and how we can translate these discoveries into improved health care.


The 200 Mammals Project

From aadvarks to wooly rats, we're working to understand mammalian evolution


Wolves vs dogs

Using domestication to investigate the genetics of early social development


Darwin's dogs

We are following the pawprints of evolution with help of dog owners around the world. We want to understand how dog DNA changed as dogs went from living in the wild to being part of our families. Do you own a dog? Join the Darwin’s Dogs project today!
