It's been a privilege & honor to serve as #NIH Director for over 12 years. However, I believe no person should hold this position for too long. So with deep gratitude to this great agency & the people who carry out its mission, I've decided to step down. nih.gov/news-events/ne…

What a fantastic leader Dr. Collins has been. The U.S. is lucky to have amazing scientists and public health professionals like him. He leaves an incredible legacy. twitter.com/NIHDirector/st…
