After pioneering several medical education efforts during and after her medical school training at the University of Khartoum Faculty of Medicine in Sudan (where she graduated in 2020), Rawan took the big geographic leap to
the Midwest to complete her pediatric residency training prior to considering a fellowship in neonatology. During her medical education, she was head of external affairs for a medical education/research organization and was a
member of the Sudanese Childhood Diabetes Association. She has strengthened her medical expertise by working in the pediatric emergency room and the intensive care unit. Currently, she runs an Instagram page that
educates new mothers on neonatal care and spread awareness on the health hazards affecting Sudan. Rawan’s training in many diverse healthcare settings (rural, urban, suburban) has fueled her commitment to bridge healthcare disparities and work towards implementing projects that help on a global scale.

Tim must have lived at least five lives prior to coming to UW—to get a full sense of everything that he experienced prior to making the leap to Madison, it’s best to bring a world map and take some time to chat with him as he describes his many life adventures. While his most recent stop was Baltimore, Maryland for research and his MPH at Hopkins, he completed his medical school training in Israel at Ben Gurion University (2015), military Medic work in South Korea (2016-2018), and lived in many different regions prior to Israel. He brings with him a wealth of multicultural and humanitarian experiences, including working in mobile clinics, researching infectious diseases to help derive ways to improve antibiotic stewardship on a large scale, and exploring opportunities for healthcare professionals to advocate for patients.

Marla Perez Negrin, MD (PGY-2)

Having grown up in Cuba where her mother served as a pediatrician, Marla witnessed the challenges of delivering healthcare in resource-limited settings. During her medical education at Washington University of Health
Sciences in Belize (2022), she emphasized the importance of community engagement and analysis of the needs of each community. Additionally, she worked and volunteered in a multitude of clinics, one of which she was able
to lead advocacy projects and work alongside healthcare professionals and community members to bring awareness and inform the public on disease prevention. Marla hopes to engage in more initiatives to narrow the health
disparity gap and improve the well-being of children.

From the Buckeye state to the cheese state, Paige is eager to learn more ways on how to care for underserved communities. As an undergraduate, Paige had the opportunity to study abroad in Botswana (2018) where she studied alongside local students analyzing the healthcare system and how to deliver care in a variety of settings. Her community engagement continued through medical school (University of Toledo, 2024) as she volunteered in
community care clinics and a local hospital’s emergency department. Paige’s experience as a pre-med mentor and serving as an organization chair strengthened her leadership role, but also taught her the value of teamwork. She hopes this track will better her skills in disease identification and management in resource-limited settings.

William Ford, MD (PGY-3)

Taking his first leap to the Midwest after training in Virginia, Maryland (2023), and Georgia, William brings with him a wealth of prior experiences, including serving in the Peace Corps in Mozambique, completing a Master of Public at Emory University (2013), and participating in multiple scholarly global health projects, including viral hepatitis surveillance in Saudi Arabia and tuberculosis screening in HIV-infected patients in Southeast Asia. William enrolled in the Global Health Track to improve his skills and knowledge relevant to providing culturally appropriate care to international populations, both within and outside the US.

Allison has decided to continue soaking up the seasons of the Midwest after attending the University of Notre Dame in Indiana (2018) and the University of Cincinnati College of Medicine (2023). Allison had the opportunity to
partake in a self-directed research project in Chiapas, Mexico. During her time in Mexico, she partnered with an organization called Compañeros en Salud (CES), where she interviewed community health workers about their
experience interacting with patients with mental illness and how they deliver mental health services to people in rural communities. During her education, she has been part of various global health organizations that discuss major
global health topics and recruit guest speakers to provide further insight. Allison wishes to continue exploring access and delivery of mental health services, and is excited to be learn more about the Madison community.

Jalal-Ud-Din completed his education in Lahore, Pakistan at the Salamat International Campus for Advanced Studies (2012) and in Karachi, Pakistan at the Aga Khan University Medical College (2017). During medical school he
worked with the Humanity Initiative, which was a student-led organization that served communities in Karachi. He has also worked with several NGOs, including Aftari on Wheels and The Sanabel Trust Foundation. Seeing the
detriment cardiovascular disease has on children is what spiked his interest in pediatric cardiology. Jalal-Ud-Din hopes to bring awareness to heart disease in children and increase access to subspecialty care.
