NIST's AI Standards Center Loses Third Director in Five Months

Chris Fall resigned as director of NIST's Center for AI Standards and Innovation on July 20, 2026, after roughly three months. No reason was given. He is the third CAISI director to depart in 2026 — David Sacks left in March, Collin Burns lasted under a week. NIST's AI standards work requires sustained, consensus-driven leadership to complete.
