I am an assistant professor in the Department of Psychology at Leiden University in the Netherlands.

I am interested in how basic processes of motivation play out at individual, interpersonal, and system (or societal) levels of analysis. My research mainly focuses on the social psychological mechanisms involved in how, why, and when people resist, provide support for, or directly engage in social change. The central theoretical framework I apply in answering these questions is “system justification theory,” which posits that people are not only motivated to feel good about themselves and the groups to which they belong, but also strive to defend and justify existing structural arrangements, including societal inequalities.

I have studied individuals’ desires to change (vs. maintain) the status quo from a variety of angles, such as (1) the influence of structural factors, (2) the underlying motivational forces, and (3) the consequences for the self and society. I have recently become interested in the self-regulatory function of system justifying beliefs and am currently investigating how (self-)stereotyping is an effective strategy in coping with norm deviance. In all of my research programs, a strong training in statistics has provided me with sophisticated tools for carrying out and interpreting complex studies of psychological processes.
