Sitara Thalia Ambrosio is a German photojournalist and visual storyteller.

Sitara Ambrosio (born as Celina Weißmann, in Fürth 2002*) reports and publishes internationally. Ambrosio grew up in a working-class family with Slovenian roots. She did not attend university, but developed her own visual language through her practical work. Her reporting focuses primarily on aspects of conflicts that are underrepresented in the media. She usually works on gender issues, migration and human rights violations - in Germany, the Balkans, Eastern Europe and the Middle East.

Ambrosio frequently integrates her work into voluntary educational programs, such as lectures and workshops at schools and youth centers. In addition to her journalistic work, she lyrically processes her experiences.

Her work is regularly exhibited and has repeatedly been awarded. In 2022, together with a team, she received the Grimme Online Award for the multimedia reportage "Kandvala". In 2023, she was awarded the Residence Prize of the Portraits - Hellerau Photography Award for "Fragile as Glass". Her photo book of the same name was published by Verlag Kettler in April 2024. The book was created in collaboration with Ukrainian journalist Yana Radchenko. Both have received the Europe-Ukraine Desk of N-Ost Border Crossing Journalism Grant for further research.

Ambrosio is represented by the agency Laif and a member of the Female Photo Club.
