My name is Marlies Maes. I am currently an assistant professor at Youth Studies, Interdisciplinary Social Science, Utrecht University, the Netherlands. I am interested in social relationships among humans and in the painful feeling of loneliness, which may arise when something is missing in those relationships. Furthermore, I love to travel and meet people from all over the world, intrigued by the similarities and differences between (but also within) cultures. In addition, I have a strong interest in methodological and statistical issues, including psychometrics and different meta-analytic techniques.
