Sinopoli was born in the Martian Congressional Republic, and is presumably early on in his national service in the Martian Congressional Republic Navy. After joining the MCRN, he obtained the rank of Ensign and was assigned to the MCRN Kittur Chennamma.

Throughout the seriesEdit
Season 3 Edit
Sinopoli was aboard the MCRN Kittur Chennamma when it was surprise-attacked by a United Nations Navy ship, which instantly severed the ship's command deck from the rest of the vessel. Railgun shots penetrated the remainder of the ship, causing it to depressurize and kill the remaining personnel on board via suffocation.
Sinopoli along with Ensigns Loftis and Ranhofer however, were grabbed by a lieutenant and sealed in an electrolysis chamber (used to produce oxygen) to survive. Although the lieutenant died from his injuries, the other three clung to life until they were rescued by Jim Holden and the crew of the Rocinante. Only Sinopoli was conscious at the time of their rescue, having been tapping SOS in Morse code on the chamber wall. Initially believing they had been saved by fellow Martians, they quickly realized they were aboard the stolen Tachi and were informed by Holden they could not leave their quarters.
Whilst confined to the medical bay, Sinopoli joins Loftis in insulting Alex Kamal, insinuating he had betrayed Mars and that unlike him their loyalty wasn't dependent on their active duty status within the MCR military. He and Ranhofer then physically attacked Kamal, whilst Loftis retrieved his pistol and declared they were going to take over the ship. Whilst Loftis held Naomi Nagata at gunpoint, Sinopoli demanded they be given access to the controls and set course for Callisto where they can rejoin the MCRN fleet headed to Jupiter.
When Bobbie Draper appears to diffuse the situation, Sinopoli immediately surrenders. Seeing that Draper is wearing Martian Marine Corps Force Recon uniform, he knew she could easily take all three of them out, and urged Loftis to drop her weapon, saying he did not want to die on the Roci. Once the hijacking attempt is neutralized, the crew of the Rocinante select Sinopoli to meet with Chrisjen Avasarala, judging him to be the most level-headed of the three ensigns. Despite initial shock and confusion, he agrees to her demands to return to the MCRN Jupiter Fleet and have his commanding officer contact UNN Admiral Souther with Avasarala's message.
