A UNIVERSITY lecturer has been committed to stand trial on child sex charges.

The academic, 52, is accused of preying on an 11-year-old friend of his daughter after they had watched the film Rio: The Movie at his home in their underwear.

He appeared in the Melbourne Magistrates Court charged with four counts of sexual penetration of a child under 16, four counts of committing an indecent act on a child under 16, and two counts of indecent assault.

The academic, who cannot be named, told the court he was not guilty of the charges.

Magistrate Donna Bakos ordered he stand trial in the County Court and bailed him to appear for a directions hearing on January 23.

Investigating officer Detective Senior Constable Alexia Bieser told the court that she interviewed the 11-year-old girl at her primary school on May 24 when she first accused the academic of interfering with her.

Detective Bieser said the girl told police she had been asleep in the academic's daughter's bedroom after watching the movie on Saturday night, May 21, when he woke her up and allegedly began touching her and kissing her. The girl said she told the academic to stop but he kept going, claiming she liked it.

When the girl was interviewed a second time, she claimed the academic abused her when she attended his daughter's birthday party in March.

Detective Bieser said the 11-year-old girl's younger sister then came forward to claim the academic had also abused her at a swimming pool in late 2010.

The detective confirmed police were seeking to take a swab from the academic as there may be DNA evidence from him on a sleeping bag owned by the girl or her family but kept at his home.

The mother of the two allegedly abused girls has filed victim compensation claims for them both.
