SALT LAKE CITY — A Cottonwood Heights man accused of viewing child pornography on a flight from Salt Lake City to Boston in November has resigned from his position as a University of Utah professor.

Grant Smith, 47, a professor of materials science and engineering, was put on administrative leave following his arrest. The university said he would be permanently dismissed if the allegations against him were true. He resigned last month, however, before any disciplinary hearings could be held, said U. spokesman Remi Barron.

"It was something he voluntarily did without any conditions," Barron said.

Smith has pleaded not guilty in Massachusetts to viewing child pornography.
