Profile
Biography
I am a behavioral scientist interested in empowering people to make better 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. I also conduct some behavioral change research on how to reduce prejudice and discrimination.

Research and professional activities
Research interests
Risk communication
Few of us can say for sure what will happen tomorrow, next week or next months, less alone predict what will happen in ten years (as for climate change). Whether events will happen or not is therefore uncertain or *risky* and is often quantified to be communicated (e.g., probabilities in weather forecasts, odds in horse races, intervals in sea rise predictions). I am researching ways to improve the communication of uncertainty and risk to help people to make better-informed decisions. Some of my projects are fairly theoretical (e.g., which vocal cues are used to mark the uncertainty of the speaker?) and some are more applied (e.g., is it better to describe the risk of drugs' adverse side effects in words or numbers?).
Gender equality
I am interested in testing evidence-based strategies to encourage people to stand up to sexism and reduce misogynist discourse (e.g., online, in magazines).
