His work focused on FDA regulatory policy and litigation. During his tenure at FDA – which included five years as head of the Office of Compliance for drugs, and three years as Assistant Commissioner for Compliance Policy – David played a leadership role in major initiatives, including the modernization of FDA's approach to pharmaceutical manufacturing quality and the agency's efforts to develop and implement a more scientific, risk-based approach to inspection and enforcement.

He also developed a deep understanding of the institutions, organizational structures, procedures, and cultures through which regulatory policy and compliance decisions are considered, developed, and implemented across all branches of government, including Congress and the courts, as well as various components of FDA, HHS, Office of Management and Budget, Department of Justice, and the White House.
