What We Do

HHRR draws upon expertise in public health research (epidemiological and clinical), exposure-related health risks (occupational and personal), hazard assessment, and underground mine safety. We provide specialized analysis, evaluation, needs assessment, training, outreach, and guidance.

We address environmental pollutants, workplace chemicals, pesticides, consumer-product chemicals, food contaminants, and diagnostic radiation. We develop and evaluate training programs to reduce workplace risks and promote community preparedness for emergencies related to chemical hazards, radiation, and bioterror agents.
