Summary

I am a behavioral scientist whose research focuses on mitigating w88 harms among people who use drugs. I have been continuously funded by the National Institutes of w88 and other funders since 2008. I use mixed methods and qualitative approaches to study the impact of harm reduction interventions, overdose prevention strategies and innovative approaches to reducing the harms associated with substance use. My current research is examining the impact of responding to overdoses on the physical, social and mental wellbeing of people who use drugs, and examining strategies to reduce w88 harms associated with methamphetamine use.
