There she worked as an advisor for the drafting of a bill for the creation of a national care system, which involved advocacy work with political, union and social leaders, congressmen and congresswomen, academics, and United Nations agencies. Celeste also writes chronicles and essays for different digital media on gender, care and political analysis.
