Dr. Ritterbusch has led social justice-oriented participatory action research initiatives with street-connected communities in Colombia for the last decade and recently in Uganda. Her work involves the documentation of human rights violations and forms of violence exerted against homeless individuals, sex workers, drug users and street-connected children and youth, and subsequent community-driven mobilizations to catalyze social justice outcomes within these communities. Throughout her research and teaching career she has explored different approaches to engaging students and community leaders through critical and responsible interaction between classroom and street spaces in Colombia and Uganda through the lens of social justice-oriented PAR. Her research has been funded by the Open Society Foundations, the National Science Foundation, the Fulbright U.S. Program and other networks promoting global social justice.
