After or shortly prior to the Eros incident, Umea was enlisted by Jules-Pierre Mao's corporation Protogen to help develop Project Caliban, a project which sought the creation of enhanced superhuman soldiers by programming the protomolecule to manipulate the biology of humans. The project was ultimately successful and resulted in the creation of several super-soldiers, which the Martian government found efficient enough to invest in the project.
In "Here There Be Dragons", Umea is seen in a flashback, where she was accompanying Doctor Strickland and Mei to the project's hidden laboratory. Having arrived there, Mei was placed on a vertical bed, presumably being thereafter injected with samples of the protomolecule by Umea.
In the present, she and her staff were invaded by Holden and his crew along with Prax. When he spotted Mei's backpack, he enragedly took a shot at one of the staff members, resulting in a gunfight which Umea was able to escape. However, follow some fumbling with a grenade then the neglect to re-lock the door behind Umea's party, the Roci crew was able to pursue and found Umea lying in a pool of blood, having been attacked by a human-protomolecule hybrid. She requested the help of Holden's crew, the latter of which refused to aid her. Defiant even when faced with death, she did not reveal any major information regarding the project, affirming only that "there is more where that came from".
