Dr. Garthe’s research examines the etiology, consequences, and prevention of youth violence, primarily among youth living in urban, low-income communities. Her research examines these topics from a developmental-ecological perspective, seeking to understand the developmental, relational, contextual, and structural/systemic factors associated with violence. Additionally, she researches dating violence and intimate partner violence, specifically looking at how definitions and responses to violence can more inclusive and accessible to historically marginalized populations (e.g., racial and ethnic minority youth, transgender populations, justice-involved women). Through this research, she has focused on guiding violence prevention efforts for youth and adults. Dr. Garthe has led and contributed to numerous research projects examining the development, implementation, and evaluation of school, family, and community-based violence prevention programs.
