Profile
Biography
I am a behavioural scientist with a PhD in socio-cognitive psychology. Over the past ten years, my work has been aimed at empowering people to make better decisions in a range of contexts (e.g., climate change, business hiring, daily sexism). This covers globally two lines of investigation: My first line of research focuses on empowering people by helping them understand uncertainty and probabilities. For example, I found that negative climate change framing (e.g., it is unlikely the sea will rise 1m vs., there is a chance it will happen) leads to more risk taking and reduces trust in case the event happen. My second line of research focuses on reducing discrimination and increasing diversity. For example, by testing how decision-making processes facilitate the inclusion of diverse candidate in hiring decisions. In my work I strive to follow best-practice scientific standards for reliable evidence (e.g., pre-registered research protocols, multi-lab replication studies, data sharing). I am interested in collaborated with external partners and I I currently have a number of collaborations with external partners focusing for example on user engagement and increasing diversity in hiring decisions.

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).
