about the lab


Our mission is to identify, develop, and advocate for equitable ways to improve population health with a focus on structurally and medically vulnerable populations. Although we have shifted some focus toward the COVID-19 pandemic, our broad areas of research are on the inequitable impact of substance use (especially opioids) and climate- and disaster-related health effects on health and mortality in the United States. Our work is applied and interdisciplinary, and we believe collaborating with other institutions, both academic and non-academic, is crucial for reducing health inequities.
