Tessie Mastorakos

Tessie is currently completing her PhD in the School and Clinical Child Psychology program at the University of Toronto (OISE). Her primary research interests are in the field of domestic violence (DV) and child maltreatment. For her Masters level research, funded by the Ontario Graduate Scholarship, Tessie investigated the relationship between attention biases and social and emotional problems among DV-exposed and non-exposed preschool-aged children using eye-tracking technology. Her research is also the first to investigate whether attention patterns in non-exposed children change after exposure to interadult anger.

Prior to attending the University of Toronto, Tessie completed her undergraduate degree at York University. Under the supervision of Dr. Robert Muller in the trauma and attachment laboratory, Tessie has examined parent-child discordance and child trauma symptomatology among children undergoing trauma therapy.

Clinically, Tessie has completed comprehensive and dynamic assessment services for children and adolescents in the educational system. She has cofacilitated an anxiety and depression treatment group for adolescents and their parents, and has worked individually and in group format with mothers and preschool-aged children exposed to domestic violence. Merging her interest in travel and working with children and families, Tessie has also worked with First Steps Kenya, a non-governmental organization based in Nairobi, Kenya. There, she co-led two programs for young mothers that focused on domestic violence awareness. She also helped manage a school for children in the Kibera Slum run by United for Parity (UFP), an organization providing relief to the least privileged families in Kibera.
