Bielsa is an architect, and she taught at the Faculty of Architecture of the National University of Rosario.

[1] Prior to the 2005 legislative elections, President Néstor Kirchner asked Bielsa to run for a highly contested seat at the national Chamber of Deputies, but she refused, stating that she had a mandate to finish her term in the office for which she was elected.

[2] Governor Obeid again asked Bielsa to run for mayor of Rosario in the 2007 general elections at the end of their term.

She did not explicitly refuse or accept that request at the time,[3] [4] but eventually other mayoral candidates presented themselves instead.
