Scott Gottlieb, a former deputy commissioner of the U.S. Food and Drug Administration, is President Donald Trump’s choice to lead the agency, according to an emailed statement from the White House.

Gottlieb, 44, who served in several senior positions at the FDA during the George W. Bush administration, has said that theories of a connection between vaccines and autism have been “thoroughly debunked.”

He has talked extensively about how to lower the cost of prescription drugs by modernizing the agency’s approval process and speeding cheaper generic competitors to market.
