The NIH director on communication with the NIH

We are committed to ensuring a safe and respectful workplace wherever NIH-supported research occurs. Be it at a recipient institution, at a conference where scientific ideas are exchanged, or in our own intramural labs, everybody deserves to work in an environment that is free of harassment, bullying, intimidation, threats, or other disruptive and inappropriate behaviors. Likewise, this goes for NIH program officers, scientific review officers (SROs), grants management specialists, and other extramural staff.
