Stella began her career at the Ministry of Gender and Community Development in Uganda engaging with policymakers for law reform, including the 1995 Ugandan Constitution, which established some of the most progressive reforms for women in the region.
She is revered throughout the region for her tireless efforts to create and enforce gender-responsive laws and policies. She played a key role in drafting Uganda’s Domestic Violence Act and in mobilizing support for gender-responsive constitutions in both Uganda and in Rwanda.
Through her work with International Center for Research on Women (ICRW), she worked on violence against children, and worked to strengthen the capacities of grassroots organizations addressing gender-based violence. She was a lecturer on gender rights and the law at Makerere University and served on the boards of Akina Mama wa Afrika, ActionAid International Uganda and the Open Society Initiative for Eastern Africa.
