I am professor by special appointment of Lesbian, Gay, Bisexual and Transgender Workplace Inclusion at Leiden University, and associate professor of social and organizational psychology at Utrecht University.

I study diversity in organizations and society and have a special interest in the social psychological mechanisms involved in how, why, and when people resist, provide support for, or directly engage in social change. In my work, I to bridge science and society with the aim of contributing to effective and evidence-based diversity policy.
