Monika Hauser is a gynaecologist specialist who has worked as a resident doctor in various German cities. Between 1992 and 1994, she worked together with women experts from Bosnia to develop Medica Zenica, a therapy centre for women which she later headed. It was in connection with this work that the medica mondiale organisation ultimately evolved. Over the subsequent six years, Monika Hauser supported the further development as a member of its board while also returning to Zenica on repeated occasions for extended missions. In 1999, she launched the medica mondiale Kosova project which entailed numerous visits to projects in Albania and the Kosovo. In 2000, Monika Hauser assumed the professional and political management of medica mondiale. As medica mondiale continues to grow into an organisation advocating human rights, she regularly speaks at national and international congresses and presents the work conducted by medica mondiale to experts and the general public.

Monika Hauser is responsible for developing the curriculum for training "psychological consultants for women" in Kosovo. Since 2002, she has also been involved in training Afghan women doctors, nurses and midwives in Kabul in her capacity as lecturer. She has received several prestigious awards such as the Gustav Heinemann Prize, the Annette Barthelt Prize and the Peter Beier Prize of the German Lutheran Church in the Rhineland as well as the Rotary Prize Trentino, South Tyrol. In 1993, she was named Woman of the Year by German ARD TV's Tagesthemen programme. She turned down the Order of Merit of the Federal Republic of Germany in protest at the German Federal Ministry of the Interior's resolution to expel Bosnian refugees in 1996. In 2008, she was awarded the Alternative Nobel Prize. Monika Hauser is one of 1,000 women to be chosen for the 1,000 Women for Peace initiative. This initiative was nominated for the Nobel Peace Prize in 2005.
