About me
I am interested in child politics in its broadest sense. I view early childhood education as both a biopolitical and national space, and childhood itself as a political form of being. I research everyday nationalism as well as childhood and children’s lives from a biosocial perspective. Within the Microbial Childhood Collaboratory, we understand the child’s body as biochemical, more‑than‑human, and porous to its environment, where biology and the biosphere intersect with social processes and power. This perspective attends to how agencies emerge, and to the matters and processes with which the biosocial child is entangled, from the microscopic to biospheric communities that undergo intensive anthropogenic changes today.
In my earlier research, I focused on children's bathrooms, everyday nationhood, Cold War divides and memories of childhood, ideologies and how knowledge production operates in academia. I am also passionate about creating kind and caring academic cultures both in our current projects, as the leader of research groups and through TRANSIT Research Centre where I am the Chair of the Steering Group.
