Epidemiology & Biostatistics

If you need to evaluate the relationship between certain exposures of individuals or a population and the disease outcomes that result, epidemiology and biostatistics can provide needed insights.

ORAU’s experts provide evaluation of the exposure-disease relationship through health surveillance programs, independent, scientific investigations, health risk assessments, and large cohort studies to inform human health protection, procedures, and policies.

Our team of epidemiologists, biostatisticians, health physicists, industrial hygienists, and toxicologists offer comprehensive expertise in epidemiologic studies of occupational exposures. This includes study design, surveys, data capture, and historical document retrieval, comprehensive literature reviews, data exploration, and health data analytics.

What is occupational epidemiology?

Occupational epidemiology describes the study of worker populations and workplace exposures, generally chemical, biological or physical (e.g., noise, heat, radiation) agents, to evaluate the risk of adverse health outcomes.

What is occupational epidemiology?

What is biostatistics?

Biostatistics involves the design, analysis, and interpretation of data to help answer important questions in medicine, public health, and biology. Such questions include what exposures or other factors contribute to development of cancer and other diseases, how long a person with a certain illness is likely to survive, or whether a new drug or treatment protocol is effective.
