Research Interests
I'm currently working as a Postdoctoral Research Fellow as part of the Social Influence and Social Change Lab at Flinders University. My research interest centres around understanding when and why people are driven to take action to achieve social change, including actions to pursue greater equality and social justice and those that seek to reverse progress towards equality and create a more hierarchical society. My work lies at the intersection between Self-Determination Theory and Social Identity Theory, and I integrate the insights of these two perspectives to understand factors that shape commitment to social movements. I use longitudinal, experimental, and person-centred methods to investigate the impacts of different underlying motives for engaging in collective action for social causes, and when such action is effective and sustained. I am also interested in processes of social influence that shape individuals’ commitment to these movements, and factors that differentiate those who engage in conventional or more radical tactics.
