A physician in the sickbay of the USS Discovery, played by Raven Dauda, who treats the crew through the Klingon war and travels with the ship to the 32nd century.
Doctor Tracy Pollard is a senior medical officer aboard the USS Discovery, played by Raven Dauda. She first appears in the first season of Star Trek: Discovery and is seen most often in the second.
With Hugh Culber dead for much of that time, Pollard carries a good deal of the sickbay's work. She treats Saru when he believes he is dying in An Obol for Charon and examines the restored Culber after his return from the mycelial network.
She remains with the ship when it jumps to the future at the end of the second season and continues to appear in later seasons, tending casualties in her brisk, unsentimental manner.
