Most recently, at the Quaker United Nations Office (QUNO) in Geneva as part of the Human Rights and Refugees Programme, Marisa engaged with a wide range of stakeholders from across states, civil society, and the UN system. In her work with QUNO, she supported the development of engagement strategies, including meaningful migrant participation, for core migration multilateral processes, particularly the Global Compact for Migration (GCM) and the International Migration Review Forum (IMRF).
At the city level, Marisa worked to advance and strengthen sanctuary practices and migrant-friendly policies in Chicago, following the lead of directly affected communities. Marisa is from Tegucigalpa, Honduras, and began her career with a focus on human rights issues related to U.S. foreign policy and military spending in Central America.

Ishimwe Jean Marie
Regional Lead, East Africa
Refugees have aspirations, dreams just like any other person in the world and should be given a central role in driving solutions to address the challenges they face, they should be heard & should be given the agency to lead.
Ishimwe is a journalist and refugee advocate with over seven years of experience in the humanitarian sector, advocating for refugee leadership and inclusive policies across East Africa.
He holds a bachelor’s degree in Journalism and Media Studies from the University of Nairobi and contributes to various media platforms to challenge refugee responses and plans that advance “savior” approaches instead of refugee- and community-centered solutions. His journey is deeply rooted in his experiences as a refugee in Kenya. Having faced numerous challenges in his early life, including a prolonged lack of refugee identity documents, he understands firsthand the hardships refugees face in accessing identity documentation. Prior to joining R-SEAT, Ishimwe served for nearly five years as the Executive Director of Youth Voices Community (YVC), where he helped guide the organization to become a leading refugee-led organization advancing advocacy, particularly around socio-economic inclusion and self-reliance in Kenya.
He is also a board advisor at YVC and Inkomoko Kenya. A believer in Pan-Africanism, Ishimwe holds that Africa’s collective consciousness in viewing refugees as brothers and sisters offers one of the strongest pathways to genuine inclusion of refugees across the continent. He currently serves as the East Africa Regional Lead for Refugees Seeking Equal Access at the Table (R-SEAT), where he works to institutionalize meaningful refugee participation and leadership at the state level across the East Africa region.
