FDA Operations Leader Butler Retiring, Agency Veteran Keller Taking Over

The Food and Drug Administration will see a leadership change next month as its chief operations officer prepares to retire from federal service.

Barclay Butler, who serves as the FDA’s deputy commissioner for operations and chief operating officer, will be stepping away from his position after holding these roles for approximately one year, according to an internal agency communication obtained by Reuters.

FDA Commissioner Marty Makary informed staff members that Melanie Keller, currently serving as Butler’s deputy, will assume his responsibilities beginning April 6. Keller brings three decades of professional experience working within the Department of Health and Human Services to her new role.

During the transition period, Butler will remain with the agency in a consulting capacity, holding the designation of COO Emeritus, before his official departure in the coming months.
