Doreen Marfo’s motivation for coming to Arizona State University is all about gaining power — for her home country. Growing up with her grandparents in Ghana, there was no access to electricity in their village. Today, the village does have electricity but the gird is by no means robust. After a summer internship at the Ghana Grid Company, Marfo is beginning her studies in the Fulton Schools to earn a master’s degree in electrical engineering with the goal of eventually working to improve the African country’s electrical services. ASU’s power systems laboratories and researchers — especially Professors Vijay Vittal and Raja Ayyanar — helped draw Marfo to the university, where she plans to join a research center and the National Society of Black Engineers.
