In the year 2141, Rao was an unspecified grade level of Admiral assigned to United Earth Starfleet Intelligence. That year, she met Dresden University of Technology computer scientist, Professor Aaron Ikerson, who had created Uraei (which ultimately led to the creation of Section 31).
During her time at SI in the 2140s decade, Admiral Rao was the liaison to Starfleet Security Captain Matthew Harris, who later became one of Section 31's senior officers. (ENT - Rise of the Federation novel: Patterns of Interference)
By 2156, Admiral Rao was in command of a division of Starfleet Intelligence. That year, she was called into the office of Admiral Ko Ji-hoon along with Professor Ikerson, where they disclosed to the Chief of Starfleet Intelligence the existence of Uraei.
Although she was originally one of Uraei's greatest champions, by 2160, Admiral Rao had a change of heart, and began meeting with Admiral Ko off the record to avoid Uraei's all-seeing eye. (ST - Section 31 novel: Control)
After the founding of the United Federation of Planets in 2161, Admiral Rao continued her career in the Federation Starfleet, later retiring from Starfleet in 2164 and moving to a house on a remote part of Mars.
Following the Ware crisis and and the discovery of Section 31's involvement in the destruction of the Partnership of Civilizations in 2165, Admiral Jonathan Archer and his closest collegues started an investigation to bring down the clandestine organization. Rao's body was discovered in her home several months dead, seemingly having committed suicide. (ENT - Rise of the Federation novel: Patterns of Interference)

Although it isn't stated specifically in Patterns of Interference, it is heavily implied that Admiral Rao didn't take her own life, but rather was assassinated by the artificial intelligence Uraei to cover its own tracks as it has done so multiple times in Control. Patterns of Interference writer Christopher L. Bennett confirms this in his annotations for the novel.
