Hi everyone! I’m a PhD candidate at McGill University, studying the ecology and genomics of rapid adaptation of stickleback in Alaska 🐟
Excited to meet some new people and hear about cool research!

We found that brain DNA methylation in guppies can shift within 30 minutes of predator exposure — with different time courses between males and females.
