She was a councilwoman in the city of Porto Alegre from 2009 to 2011 and later became a state deputy in the state of Rio Grande do Sul from 2011 to 2023. She is currently affiliated with the Democratic Labour Party (PDT), which she has been affiliated with since she was 18 years old. She is the granddaughter of Leonel Brizola, as well as the sister of fellow politicians Brizola Neto and Leonel Brizola Neto, being the twin sister of the latter.

Leonel de Moura Brizola was a Brazilian politician. Launched into politics by Brazilian president Getúlio Vargas in the 1930–1950s, Brizola was the only politician to serve as elected governor of two Brazilian states. An engineer by training, Brizola organized the youth wing of the Brazilian Labour Party and served as state representative for Rio Grande do Sul and mayor of its capital, Porto Alegre. In 1958 he was elected governor and subsequently played a major role in thwarting a first coup attempt by sectors of the armed forces in 1961, who wished to stop João Goulart from assuming the presidency, under allegations of communist ties. Three years later, facing the 1964 Brazilian coup d'état that went on to install the Brazilian military dictatorship, Brizola again wanted the democratic forces to resist, but Goulart did not want to risk the possibility of civil war, and Brizola was exiled in Uruguay.
