U.S. Food and Drug Administration (FDA) commissioner Margaret Hamburg Thursday told employees that she is resigning from her post in March.
Hamburg told the employees in an email that the agency's chief scientist, Stephen Ostroff, will serve as acting commissioner. Hamburg has served as commissioner since 2009.
In the email, Hamburg highlighted her work in creating a new food safety system, advancing the safety and effectiveness of medical products, and putting new tobacco regulations in place.
