Hi, I'm Roos.
I help organizations understand and change behavior – translating behavioral science into products and interventions that actually work. I’ve worked on topics like cybercrime, digital security, and financial decision-making.
For a while I tried the digital nomad life, but honestly: working on a sandy beach without WiFi sounds better than it is. These days I’m based in Amsterdam, though still open to international and remote collaborations.
When I’m not working, you’ll probably find me in the kitchen. I bake bread with my 40-year-old sourdough starter (crispy crust included), love cooking for friends and family, and spend as much time as I can reading, working out, traveling, and being outdoors.
