Homie Razavi

Homie A. Razavi is the founder and managing director at the Center for Disease Analysis (CDA), an organization specializing in studying complex and poorly understood diseases. CDA’s goal is to study and publish data to help educate stakeholders and support decision-making in different countries.

Since 2008, Homie has led a team of epidemiologists and modellers to quantify epidemiology of hepatitis, forecast the future disease burden and help countries develop national strategies. His team has been responsible for the development of a number of mathematical models currently used by countries to develop intervention strategies for hepatitis. In addition, his team has developed the Polaris Observatory, which collects and reports HCV, HBV and HDV epidemiology, disease burden and treatment rates for all countries.

He has a broad background, which includes basic research, commercial development, portfolio management, and decision analysis.
