Professor Yu Cheung served as Chief Data Analyst on Innes Station.
She began her work on Innes Station in around 2200, under a five-year contract. In 2203, she was part of Otto Nielson's attempted cover-up following his murder of Linda Ihejirika, even threatening Sabina White at gunpoint. However, she was subdued by "The Colonel".
Cheung was sentenced to sixteen years imprisonment for attempted murder and aiding an offender.
She later resurfaced on Prison Station 13, where she was cooperating with the Jovian Astrolaw Commission in their attempts to frame Gail Pilgrim for the murder of Ihejirika. She was set free after Gail was found guilty, but it is not known what became of her after that.
