Area(s) of Specialization:
Opioids and other substances of abuse; women’s health; life course; social determinants; health services utilization and outcomes
I research how health care systems and public policies can better promote health and wellness among vulnerable and underserved populations, particularly for individuals at risk for substance use disorders, mental illness, and infectious diseases. Most recently, I have investigated the health services utilization and long-term outcomes of patients treated for opioid use disorder, the behavioral health effects of childhood adversity over the life course, and gender differences in use of complementary and integrative healthcare by military veterans with chronic musculoskeletal pain. I utilize both qualitative and quantitative methods, and much of my research has originated from longitudinal study designs and creating knowledge via mining of linked administrative “big data” provided by health care delivery organizations, social services systems, and criminal justice sources. Currently, I am principal investigator on a pilot study in which I am adapting digital storytelling methods with and for women treated for opioid use disorder to support medication adherence and improve community integration. I am also leading a project funded by The Greenwall Foundation in which I am exploring shared decision-making as an ethical response to the opioid crisis. I am co-Investigator of a NIDA-funded investigation of opioid use and treatment utilization by adults with opioid use disorder released from jail. I am Principal Investigator of the evaluation of a SAMHSA/CSAT-funded project to expand access to medications to criminally-involved individuals with opioid use disorder.
