His role included directing a systematic and highly productive program of research aimed at improving the scientific validity and clinical utility of the ICD-11 diagnostic manual corresponding to these areas, incorporating a range of innovative methodologies.

As a part of this effort, Dr. Reed founded, developed, and directs the Global Clinical Practice Network (GCPN; to participate in ICD-11 studies.

He has received numerous awards, most recently the Robert L.
