Ryle Simons was a male Human from Alpha Centauri. Simons was held the rank of Ensign in Starfleet.
Two weeks after his gradution from Starfleet Academy in 2374, Simons was on Deep Space 9 awaiting his assignment to the USS Destiny. When the alignment of the Red Orbs opened Jalbador and destroyed Deep Space 9, Simons was among those rescued from the station by the crew of the USS Defiant. As Simons had a minor in Warp Theory, Benjamin Sisko assigned him to make repairs in Engineering. (DS9 - Millennium novels: The War of the Prophets, Inferno)
