Profile
Biography
I am interested in empowering people to make better decisions. My main research goal is to develop better uncertainty communication methods to help people make better-informed decisions. For example, I evaluate whether different weather forecast formats reduce weather misinterpretations and how different framing of climate change uncertainty affects decision-making quality and trust.
