Miranda Lawson

Miranda Lawson  is a human Cerberus Officer. As Jacob Taylor's informant, she gives him guidance and advice during missions, often via hologram. Miranda is very well traveled and has many contacts, extending from Citadel space and the Terminus Systems, to as far as the hostile Nemean Abyss. Her vast network of contacts may be explained by the fact Miranda is a known Cerberus operative, one who still has friends — or at least friends of friends — in the Alliance military.

History
Miranda was born in 2150. As she explains to Shepard, Miranda never had a mother, only a father who is extremely influential, wealthy, and ego-maniacal. Using a modified copy of his own genome, Miranda was genetically engineered to be a specimen of human perfection. She never had a mother, as she was not conceived naturally. She was not the first "daughter" he ever designed, just the first he kept. Everything, from her intelligence, physical constitution, biotic abilities, to her appearance were designed before birth to be excellent. She boasts about being able to shoot a mech's head off from 100 meters away or just as easily crush it with her biotic powers. Miranda also heals faster than other humans and will probably live half a lifespan longer. If Shepard accuses her of being cocky, she retorts that she's only stating the facts.

However, Miranda’s gifts were a burden growing up. Despite her accomplishments, Miranda’s perfectionist father never showed approval or pride towards his daughter. He always expected more and better from her — forever chiding her to be greater than she already was. He also imposed a very strict lifestyle on Miranda, and forbade her from making friends and having a social life. Miranda remarks that he didn't want a daughter as much as a dynasty, which was why he used his own genetic template to create her. The constant pressure and lack of affection led Miranda to relinquish her privileged lifestyle and run away from home as soon as she could — although some gunfire was involved. Her father used his extensive network of contacts to chase her across the galaxy, but she managed to elude him nonetheless.

At some point Miranda approached Cerberus and joined them in exchange for protection. Miranda knew of them since her father sympathized with their human-centric agenda and was a major backer. When she enlisted with Cerberus, he stopped pursuing her but severed his ties to the group. Despite their past dealings with her father, Miranda agrees with Cerberus' desire to help humanity. Miranda also enjoys the opportunity to work with people as smart as she is and the amount of latitude their clandestine operations afford her; she is given an objective, all the resources she needs, and nothing more. Evidently, Miranda has advanced far enough to become one of the few in the organization, much less the galaxy, that meets and answers directly to the Illusive Man, who appreciates her abilities.

After Cerberus gains possession of Commander Shepard's corpse, the Illusive Man selects Miranda to be the head of the Lazarus Cell and puts her in charge of the Lazarus Project. Over the course of two years, Miranda oversees the development and implementation of Cerberus' vast resources towards bringing Shepard back to life.
