(written from a Production point of view)
Eugene Wesley "Rod" Roddenberry Jr. (born 5 February 1974; age 47) is the only son of Star Trek creator Gene Roddenberry and his second wife, Majel Barrett-Roddenberry. He has two sisters, Darleen Roddenberry and Dawn Roddenberry, both from Gene Roddenberry's first marriage to Eileen Anita Rexroat. He has a wife, Heidi, and a son named Zale.  Roddenberry is the chief executive officer at Roddenberry Entertainment, a company through which he is producing the newest Star Trek series Star Trek: Discovery and Star Trek: Picard.
Interactions with Star Trek
Roddenberry acted as a consultant on, advocate for, and promoter of the fan-made Star Trek: New Voyages series.
He worked as an uncredited Art Department production assistant on either Star Trek: The Next Generation or Star Trek: Deep Space Nine for at least a year in the mid-1990s. Reportedly the registry number for the USS Defiant (NX-74205) was taken from Roddenberry's birthday (02/05/74), much as the registry of the USS Bonchune was taken from Robert Bonchune's birthday. (Star Trek Encyclopedia (4th ed., vol. 1, p. 196))
Roddenberry was interviewed in the second season episode of the Netflix series The Toys That Made Us that focused on Star Trek toys and models. In this interview he described how he made the model of the Constitution-class that was painted silver and then used as a set piece on various TNG episodes.
The "Trek Fish" variant of the "Jesus Fish" (Ichthys symbol) car bumper ornament was designed by Roddenberry.
On 3 March 2016, it was announced that he would be one of the co-executive producers of Star Trek: Discovery,  but is now actually credited as an executive producer on the series as well as on After Trek. Roddenberry also serves as executive producer on the companion series, Star Trek: Short Treks, and on the forthcoming series Star Trek: Picard, Star Trek: Lower Decks, and Untitled Section 31 series.
He wrote an episode of the science fiction series called Earth: Final Conflict, which was a project conceived by Gene Roddenberry in the 1970s and produced by Majel Barrett Roddenberry in Toronto starting in 1997.
Roddenberry has also been involved with a large number of real-world science endeavors including The Ansari X-Prize, NASA, JPL, The Planetary Society, The Roddenberry Dive Team, and the Kennedy Space Center.
