EpidStrategies is founded on rigorous scientific principles that guide our research on complex health conditions. With a focus on pharmaceuticals, medical devices, nutritional products, and environmental chemicals, EpidStrategies consulting scientists aid clients in the conduct, evaluation, and interpretation of epidemiological studies. Our research frequently results in peer-reviewed publications and presentations at scientific conferences and is also used in numerous regulatory documents in the US and Europe.
