Research Interests
I am interested in investigating the social psychological processes undergirding both historical and contemporary political and intergroup conflicts using lenses provided by moral and political psychology, and intergroup relations.
One line of my research seeks to understand the psychological legacies of historical atrocities. In my recent work, I have investigated the psychological conditions in which people blame current groups for the wrongdoings of that group’s past. My work on historical blame so far can be found here.
​
In another line of work, I am interested in understanding the psychological contributors to intergroup divisions such as political and religious divisions. In one of the projects in this area, I am developing a new construct moral humility. One of my papers on moral humility can be found here. In other papers, i) I build a psychometrically validated measure a moral humility and test its construct validity, ii) develop interventions to change moral humility and test its impact on important outcomes, iii) explore the importance of moral humility.
Relatedly, I am also working on understanding the psychological predictors of political polarization and democratic outcomes. In one of the projects, I test whether affective polarization can predict democratic performance at an institutional level in the US.
​
Finally, I’m also interested in and work on belief systems. This involves understanding the causes and consequences of the way people’s beliefs systems are structured and undergo change. I am studying this in the context of political and religious beliefs.
