Rosi studied International Law and International Relations in Europe and the Middle East. She further has been involved in development projects since 2006 when she volunteered at Child & Family Welfare in South Africa working with traumatized children. Apart from development work, she has vast experience in conducting research: in 2007 she worked as an External Researcher for the Norwegian International Peace and Research Institute of Oslo (PRIO). There she conducted research on the conflict dynamics in Cyprus. When she was the Personal Assistant to the CEO of AMREF (African Medical and Research Foundation) Germany, she gained insight into managerial tasks of an NGO as well as into different issues of third world countries in Africa and the problems the continent is struggling with. Most recently, Rosi worked with UNDP and UNHCR where she improved her interviewing skills, practised implementing development projects in conflict sensitive areas as well as perfecting her organizational skills.
