My research focuses on the role of support networks and informal caregiving relationships in disadvantaged populations' health services utilization and adherence to medical regimens, and the impact on quality of life of caregivers and care recipients.  Most of my work has focused on persons with HIV/AIDS and/or substance addiction. Major interests are structural approaches to linking persons with co-occurring disorders to medical and addictions care and treatment, and promoting caregiving relationships to facilitate medical adherence and quality of life. 

Currently I am conducting an interagency collaborative study to identify substance using EMS patients and link them to care and treatment.  I am also conducting a study with colleagues at JHSOM and SON exploring continuity of informal HIV caregiving relationships, interpersonal communication with formal and informal caregivers about end of life care preferences,  and the implications for HIV palliative and end of life care.
