President-elect Donald J. Trump late Tuesday nominated Jay Bhattacharya, M.D., Ph.D., professor of health policy at Stanford’s School of Medicine, to lead the National Institutes of Health (NIH).

The NIH — the “nation’s medical research agency” — oversees 27 separate institutes and centers and controls a budget of nearly $48 billion. It is a division of the U.S. Department of Health and Human Services (HHS).

“I am thrilled to nominate Jay Bhattacharya, MD, PhD, to serve as Director of the National Institutes of Health,” Trump announced on X. “Dr. Bhattacharya will work in cooperation with Robert F. Kennedy Jr. to direct the Nation’s Medical Research, and to make important discoveries that will improve Health, and save lives.”
