The New Hampshire Board of Medicine has ordered an emergency suspension of Dr. Richard Keller’s medical license in that state and opened a case about the charges he faces in a Massachusetts federal court. The former medical director of Phillips Academy in Andover was arrested at his home on Sept. 13 and charged with receiving child pornography.

Keller has been licensed to practice in New Hampshire since July 2002. The board had no record of him working in that state, a board administrator said. The board scheduled a hearing for Oct. 3 at noon.

Keller drew the attention of federal investigators after his name turned up in the customer database of a foreign company that produced child pornography, according to an affidavit filed in federal court. Investigators searched his home and found dozens of DVDs and hundreds of sexually explicit photographs of children, prosecutors said.

Keller has been placed on leave from his roles as a part-time pediatric endocrinologist at Boston Children’s Hospital and as an instructor at Harvard Medical School. He also worked at a summer camp in the Berkshires and served for nearly three decades at Camp Joslin in Charlton for boys with diabetes, owned since 2010 by the Barton Center for Diabetes Education.

Keller last week agreed to stop practicing medicine in Massachusetts until the Board of Registration in Medicine takes further action. On Friday, he also waived his right to a detention and probable cause hearing in federal court and may be detained until trial.
