Welcome to my personal website.
I am an associate professor of methodology and statistics in a psychology department. The dice you see at the left is often used in classical statistical textbooks to explain

random variables and probability

. The dice also represents a choice mechanism with a

categorical outcome

, one of my main research interests.
In psychology the dice is often not fair: some sides are heavier than others, or stated differently, some options have a larger probability. The main task then is to estimate these probabilities and to link them to known characteristics of the participants under study.
