I conduct mixed methods social network research using health behavior theories to examine the individual, social, and environmental factors associated with opioid overdose and HIV among people who use drugs and other groups at risk. In 1999 I started working with syringe access programs to identify ways to reduce risk for HIV among people who inject drugs. Since 2006 I have studied opioid overdose, with a focus on programs to expand access to naloxone, reduce opioid overdose deaths, and increase access to effective, evidence-based treatment. Through my research, I collaborate with clinical, social service, public health, behavioral health, and criminal justice stakeholders to identify factors that elevate the risk for negative health outcomes, evaluate innovative programs to reduce HIV transmission and overdose, and inform public health policy making.
