Research Interests:

Child/Adolescent Depression, Cognitive Models of Depression Risk, Schema Theory and Therapy, Emotional Resilience, Positive Clinical Psychology, Childhood Maltreatment, and Innovative Online Interventions for Building Emotional Resilience in Youth

Dr. Lumley’s career ambition is to significantly further understanding of factors that predict youth depression and foster emotional resilience for youth, even those most at risk. Her clinical/developmental research considers the child as a whole person, assessing strengths and positive outcomes along with psychopathology, uniquely examining risk and resilience alongside one and other bridging psychopathology, developmental psychology and positive psychology paradigms.

By developing and rigorously investigating mood psychopathology theory and its application to innovative intervention, she aims to make a significant contribution to challenging depression and promoting positive emotional functioning for children and adolescents.
