About me

I am a researcher in social psychology, currently working at Igonogo and associated to the LIP/PC2S laboratory (Univ. Grenoble Alpes).

My research interests include 'implicit' social cognition, carbon footprint metacognition, methods in psychological science, and data analysis.

I mainly work on the processes underlying approach/avoidance tendencies. I also have a research project on carbon footprint metacognition and I participate in some multi-lab experiments with the Psychological Science Accelerator.

Beside my professional activities, I am concerned about climate change and related topics such as energy supply or biodiversity.

Test your CO2 metacognition
Do you know how accurate is your knowledge on CO2 emissions? Take part in the META-CO2 experiment to have some feedbacks.

Carbon stripes
Inspired by the warming stripes of Ed Hawkins, the carbon stripes represent yearly CO2 emissions through stripes and the remaining CO2 budget of the 1.5°C and 2°C scenarios with dotted lines.

What simple effects can't tell
Often, people interpret an interaction based on simple effects. This post aims at showing that this kind of practice is to be avoided because simple effects also depend on main effects.

Projects

META-CO2
To reduce our carbon footprint we should know to what extent our behaviors emit CO2. Better, we should know whether our knowledge on CO2 emissions is reliable. This project aims at evaluating people’s metacognition on CO2 emissions.

Approach/avoidance effects and memory processes
Approach/avoidance is a primary response of an organism. This research project aims at understanding better the memory processes underlying these action tendencies.
