Exposure science examines the ways in which individuals encounter and are exposed to physical, chemical, biological and other stressors in both general environments and workplaces. Within epidemiology, exposure assessment is crucial to identify specific exposure agents and determine their impact on mortality/morbidity across varying populations—be it a community, city, state or country.

The Human Exposure Assessment Lab (HEAL) is dedicated to precisely measuring the exposure of populations to both chemical and non-chemical stressors across time and space, as well as discerning the subsequent effects on health. Furthermore, HEAL is committed to devising and enacting evidence-driven interventions aimed at mitigating these exposures, particularly among at-risk populations in Philadelphia, USA, and beyond.
