By 2263, Masada held the rank of lieutenant, and served as science officer and second officer of the USS Constellation under Commodore Matthew Decker. In that year, during the survey of Ravanar IV in the Taurus Reach, he discovered a mold containing an anomalously high count of chemical base pairs. Masada determined, that the Constellation's lab facilities were inadequate to pursue the matter, so Commodore Decker decided to transmit their findings to Starfleet Command. (VAN novel: Harbinger)
