Regulatory Science is the field that focuses on developing and applying scientific methods to ensure the safety, efficacy, and quality of products, particularly in the areas of pharmaceuticals, medical devices, and food. It involves the evaluation of data and research to inform regulatory decisions made by agencies like the U.S. Food and Drug Administration (FDA). This discipline bridges the gap between scientific research and regulatory policy, ensuring that new products meet established standards before they reach the market. By integrating various scientific disciplines, regulatory science helps protect public health while fostering innovation in product development.
