My research lies at the intersection of social-psychological research on stereotyping and prejudice, cognitive psychology, and methodology. In my work, I use basic laboratory methods to study attitudes and social cogniton as these topics pertain to  broad questions of intergroup relations, stereotyping, prejudice, and other social topics in modern societies. Discussions around these social problems are often replete with assumptions about human cognition, such as claims about inequality stemming from “unconscious racism”, or claims that people should be more or less “colorblind” or “multicultural”. My contribution to these debates is to ask: What are the empirical grounds for such claims? On what assumptions about basic human cognition do they rest? Are those assumptions justified given the available evidence? Using experimental laboratory methods, I try to advance our understanding of the cognitive processes involved in intergroup relations and attitude expression to apply them to relevant questions and challenges we experience in our current societies.

I am looking for doctoral students interested in social cognition. I supervise quantitative projects (lab and online studies) concerned with the cognitive underpinnings of processes related to attitudes and stereotypes and prejudice. My currently most active line of research is concerned with awareness and implicit measures of attitudes and stereotyping and prejudice.

I would not be the right supervisor for qualitative research projects.
