Amrita Srinivasan

Dr. is a specialist in metabolic disorders at Johns Hopkins Medical Center. "She's fiftyish, round-faced, plump, vital, with a buttery brown complexion and gleaming gray-shot black hair that suggest Indian or Pakistani ancestry." 

She is also an "old friend" (and possibly a current or former romantic interest) of Stephen Reyes. Reyes considered asking Amrita to help stand the 24-hour vigil over Chaz Villette while he was unconscious. Later, she joined Chaz's care team. 

She is the "guy Falkner and Reyes know at Johns Hopkins... who worked out the basic demands of the anomaloid metabolism for Reyes, back in the day." In the DVD extra "Tactics", she is one of the people mentioned by Victor Celentano as he lists the financial costs associated with the government's response to the Anomaly.
