Dr. Juli Mizrahi (née Niwashiro) heads investigations into the appearances of the alien scourge called the Gnosis. She formed the Subcommittee on Close Encounters, also known as the S.O.C.E., in T.C. 4754 following increased Gnosis activity after the Miltian Conflict. Based in Galaxy Federation planetary capital Fifth Jerusalem, she is the ex-wife and widow of scientist Joachim Mizrahi. Joachim co-created MOMO Mizrahi with Juli. Juli is a famous scientist and knows about cybernetic engineering, although Juli believes "infamous" is more appropriate than "famous".
