Designing for Health: Stephanie Carreiro, MD | Emergency Medicine Physician and Medical Toxicologist at UMass Medical School |

In this episode of Designing for Health, Craig Joseph sits down with Dr. Stephanie Carreiro, an emergency medicine physician and medical toxicologist at UMass Medical School, to explore how digital health tools can be thoughtfully designed to support people with substance use disorder. Dr. Carreiro shares her journey into toxicology and addiction research, and explains how wearable sensors, mobile apps, and digital biomarkers can detect stress, craving, withdrawal, and other physiologic signals related to substance use. The conversation covers everything from wearable design pitfalls and privacy concerns to the idea of “digital dosing,” peer recovery coaches as key users of health data, and why empowerment not enforcement must be at the center of addiction technology.
