Sister Mary Scullion is the internationally recognized founder of Women of Hope, which works with homeless women, the Outreach Coordination Center for those living on the streets of Philadelphia, and Project H.O.M.E., which provides integrated services to the homeless. Her fellowship goal was to find ways to help the homeless breach the digital divide. She visited successful technology-based learning centers in Hungary and Italy to identify best practices. Upon her return to Philadelphia, she used what she had seen in the 2004 establishment of The Honickman Learning Center & Comcast Technology Labs, a three-story mega-center loaded with state-of-the-art hardware and software education systems for Project H.O.M.E. clientele.

Dr. Abdul Bari Khan used his fellowship to further his vision for a hospital in Karachi that would deliver free, high-quality health care to the poor. Using the advice of the numerous U.S. health care professionals he met, he opened the Indus Hospital in 2007. He returns to the U.S. annually to collect donated hospital supplies and to persuade doctors to give their vacation time to volunteer at Indus. More than 600,000 people have received free treatment at Indus, which is Pakistan's first paper-free hospital and first to use mobile and GPRS technologies treat people in remote, inaccessible communities.

Dr. Sam Thenya is the CEO of the largest indigenous private hospital chain that also cares for abused persons free of charge in Kenya. He came here to look at healthcare management, ranging from in-store clinics for non-urgent primary care to delivery systems for marginalized communities. He said his fellowship taught him that he "was not thinking big enough." Upon his return home, he restructured his hospital and acquired two new ones, using advice from hospital administrators he met in the U.S. One of those administrators is a 2011 USA Fellow, and Dr. Thenya oversaw his fellowship program in Nairobi. Contacts Thenya made during his fellowship have enabled him to model a soon to be launched school of nursing at the hospital.

Tri Mumpuni Iskandar harnesses technologies to empower Indonesians. Her fellowship allowed her to connect with Cornell, Stanford and Colombia, yielding initiatives such as the Entrepreneurial Design for Extreme Affordability program to bring electricity to remote island locations. Her follow-up visits to the U.S. deepened her links here and resulted in her appointment as Vice Chair for the Indonesian Chapter of Partners for a New Beginning, a program initiated by President Obama to strengthen ties between the U.S. and Muslim communities. She is a 2011 winner of Asia's prestigious Magsaysay Award for harnessing the energy of water stored in dams to bring electricity to half a million people.

Hae Eun Kim is a prominent cellist with a Ph.D. from the Yale School of Music, who found that Korea's only source of Western classical music -- two large municipal symphonies -- were not enough to satisfy music lovers' appetite or performers' desire to play for audiences. She came to the U.S. to learn how to organize other kinds of music groups, from chamber orchestras to string quartets. She is now securing financial sponsors, marketing experts, and artists who share her vision. She persuaded the Korean National University of Arts to establish the Careers and Professional Development Program, an Arts Leadership Program, and an Entrepreneurship in Music Program to help students learn how to turn promising ideas into enterprises that create value.

Chris Nowinski met with leaders in sports and sports medicine throughout Western Europe to promote ways to address concussions and Chronic Traumatic Encephalopathy (CTE), a degenerative brain disease that affects athletes who suffer multiple concussions. As a result of his fellowship, he is developing an international brain bank initiative between his non-profit Sports Legacy Institute, Boston University School of Medicine, and researchers in Dublin and Munich. Chris plans travel to begin a media campaign and will serve as an advisor to his new European counterparts. He was also invited to return to the 2012 International Symposia on Concussion in Sport meeting by theInternational Olympic Committee to help devise new guidelines to address concussions, including addressing substitution rules in rugby and FIFA events.
