The first midwife to graduate in Chad, from the 1990s until her death in 2011, she led several public health initiatives on behalf of the government of Idriss Déby.
[1][2] On 4 December 1990, Gossingar was named as the Secretary State for Public Health with Responsibility for Social Affairs and the Promotion of Women, a role she occupied between 1991 and 1993.
Part of the International Planned Parenthood Federation, Gossingar advocated for the widespread availability of reproductive health across Chad, often with limited financial support.
She also challenged traditional norms around promoting fidelity and abstinence with regards to family planning and sexual health, which she felt did not work in contemporary Chadian society.
Gossingar felt that support needed to be spread all over Chad, particularly in rural areas which had a lack of medical facilities; she also believed outreach work was required to challenge traditional patriarchal systems that prevented women from making decisions concerning their pregnancies and childbirth.
