The Biologist is the narrator and protagonist of Annihilation, the first book of the Southern Reach Trilogy, which tells the story of the 12th Expedition, of which she was one of four members. As with the rest of her colleagues, her name is not given in the first book. A physical description of her doppelgänger, Ghost Bird, is offered in the second book:
—Control in Authority.
She is one of the few characters known to have survived for a long period of time inside of Area X, entering via her expedition and later becoming a gigantic creature with thousands of eyes, which Control and Ghost Bird encounter in Acceptance.
—The Biologist in Annihilation.
One of her recurring personality traits in Annihilation is her fascination with nature, particularly with the study and observation of animals in the micro-ecosystems around her. In her journal, she mentions an abandoned pool in one of her childhood homes, a puddle near her adult residence, and a college-required field assignment in Rock Bay as examples. It is likely that these spaces offered distraction and calm when the outside world became too overwhelming.
In her own descriptions of her life before the expedition, the Biologist describes herself as an introverted person with little social life, unlike her husband, who was very sociable and had many friends. Her socialization was mostly limited to her husband's gatherings with his friends, earning the nickname "Ghost Bird", which later became the alias of her doppelgänger.
- While other members of the expedition refer to a certain structure within Area X as a "tunnel," the Biologist adamantly refers to it as a "Tower".
- Although her physical appearance is never clearly described in Annihilation, she is able to overpower the surveyor, who is the soldier of the expedition. Control also notes that she (Ghost Bird) must be close to his height of six feet tall, and perceives her as "physically strong" when he notices her thick muscle between her neck and her shoulders. However, it's unclear if this is consistent with the Biologist's physique, or a result of Ghost Bird being left with nothing to do but eat and exercise in the Southern Reach facility.
- While preparing for her participation in the twelfth expedition, the Biologist imagined and dreamed about an enormous monster emerging from the ocean next to the team's camp, foreshadowing her eventual fate.
