Mabheka is dedicated to public service, and he has advocated for poverty eradication at the United Nations Secretariat briefings and raised public awareness about world problems including Poverty and HIV-AIDS, and Human Trafficking through public forums at the Student World Assembly. In 2005 and 2006, he participated in the prestigious Naval Academy Foreign Affairs Conference and the Student Conference on United States Affairs, where his roundtable discussed Zimbabwe as a case study.
In the area of poverty, Mabheka plans to work with the Acumen Fund with a goal to introduce the “Blue Sweater” method in Zimbabwe, “a new approach to solving poverty – using patient capital to identify, support and grow businesses that can effectively and sustainably serve the poor” (see http://www.acumenfund.org/bluesweater/). Currently, he is volunteering at the International Rescue Committee, an organization whose mission is to provide emergency relief, post-conflict development and resettlement services; to work for the protection of human rights; and to advocate for those uprooted or affected by violent conflict and oppression.
His research interests include poverty, HIV/AIDS and international sanctions. Mabheka is currently conducting research on The Impact of Economic Sanctions: the Case of Zimbabwe with the CUNY Macaulay Honors College which will culminate in a presentation at the Ithaca Undergraduate Conference in March 2011, under the instruction of Distinguished Professor Lee Quinby and Professor Vincent Boudreau, Political Science, City College. In addition, Mabheka was awarded the Colin Powell Fellowship award and has the honor of being a fellow at the Colin Powell Center for Policy Studies at City College.
