UnitedHealth Group said on Tuesday it had named former US Food and Drug Administration commissioner Scott Gottlieb to its board, effective immediately.

Gottlieb, who had served as the FDA chief from 2017 to 2019, stepped down abruptly in 2019 and joined the board of U.S. drugmaker Pfizer (PFE.N),late r that year.

“I hope to leverage my experience to support providers in their delivery of care that’s not only more innovative but also more affordable, and that improves outcomes for patients and communities,” Gottlieb said in a statement.

Gottlieb was well regarded by public health advocates and won bipartisan support for his efforts to curb use of flavoured e-cigarettes by youths, speed approval times for cheap generic medicines to increase competition and bring down drug prices.
