"The government believes that the position of trust and responsibility the defendant was given in regards to young and vulnerable children heightens his culpability in this case and warrants a significant term of incarceration," Assistant U.S. Attorney Heather A. Hill said.
Pelloski headed the pediatric radiation-oncology program at the Arthur G. James Cancer Hospital at Ohio State University. He admitted when he pleaded guilty last year that he downloaded pornography on a university laptop as well as on his home computer.
Defense lawyers said Pelloski had been sexually abused when he was a child and called his pornography consumption "a misguided attempt at processing his own abuse and repressed memories."
Pelloski agreed last year to the indefinite suspension of his Ohio medical license.
