She was the grand daughter of Doctor Simon Van Gelder and followed him in the psychological field. Eventually, she became the project leader that was responsible for the creation of the first practical Holodeck for the United Federation of Planets.

She later pioneered other practical applications of this new holodeck technology. This led to it being used for training, amusement, theater as well as scientific applications.

Simone later became the head of the Holographics Universal Corporation and was in a permanent contract with Starfleet where she charged with continued research for modifying as well as improving holodeck designs that were used on Federation starships.

She was also a student of clothing from various Terran historical eras and had written a monograph on emotional/psychological impact that clothing that was provided by society had on individual lives.
