Her program of research centers on individual- and system-level factors that affect the wellbeing of women victims of intimate partner violence (IPV). At the individual level, she conducts risk and protective factor research and applies micro-longitudinal designs and is particularly interested in conducting research that informs the development of interventions to be implemented in community settings. Specifically, Dr. Sullivan focuses on advancing knowledge of IPV, posttraumatic stress, substance use, and HIV/sexual risk – as well as other co-occurring problems. At the system-level, she focuses on understanding the capacity of systems (e.g., criminal justice system) to meet the unique needs of IPV-exposed women.
