A common question among applicants is “what are your graduates doing now?” Since graduation, Global Health residents have pursued a wide variety of fields of work and study – from fellowships to research to clinical jobs – in a wide variety of locations, from cities around the US to countries around the world. The majority have chosen a career with continued involvement in global or community health. Here, a few of our graduates speak about their experiences in the Global Health Track and what they have done after.

Temidayo Fadelu, MD

Adult Oncology Program Officer, Partners in Health (PIH)/Inshuti Mu Buzima (IMB) - Rwanda
Associate Physician, Brigham and Women's Hospital
Instructor of Medicine, Harvard Medical School

I came to Penn for residency because of the appeal of the Global Health track. Being originally from Nigeria, I sought opportunities to return back to somewhere in Africa during medical school and residency. My international rotation was at Mbagathi District Hospital in Nairobi. It offered a good mix of clinical experiences, involvement in education as well as a grounding to understand the larger health care system.

My clinical interest is in cancer. After the completion of residency, with the aim of melding my interests and getting more on the ground experience, I took a position with Partners in Health in Rwanda. I do a mix of clinical and programmatic work for a novel non-communicable disease care delivery program. With a task-shifting model, we deliver oncology care in a rural setting. I interface with expert oncologists and clinicians based in Boston, policy makers within the Ministry of Health in Rwanda, and local clinicians to provide care and build local training infrastructure. I also spend a small fraction of my time as a hospitalist at Brigham and Women’s Hospital and as a mentor for upcoming trainees interested in global health.

I intend to pursue a fellowship in oncology and make a career doing global oncology implementation in Sub-Saharan Africa.

Alithea Gabrellas, MD

Interim Chief of Internal Medicine, Tsehootsooi Medical Center
Navajo Reservation, Arizona

As a global health and primary care track resident I worked at Puentes de Salud Clinic, served as firm chief of the Refugee Health Clinic and did rotations in Botswana during residency. I currently work at Tsehootsooi Medical Center (Fort Defiance Indian Hospital) on the Navajo Reservation in Arizona. I do traditional internal medicine (inpatient and outpatient) and run the TB and HIV clinics. I hope to be welcoming global health track residents to my site soon for rotations. My experiences in the global health track as a resident prepared me very well for this career in a "global health" setting within the United States.

Gayani Tillekeratne, MD

Global Health Fellow, Duke University School of Medicine
Durham, North Carolina, USA

As a participant in the Global Health Equities Track (and later as an Infectious Diseases fellow), I had several opportunities to visit Nairobi, Kenya and participate in clinical care, education, and research. My initial visit consisted of offering health screenings for patients in the Kibera slum, where basic preventative care is often lacking, and leading educational workshops for community health workers. During a later visit, I helped set up cervical cancer screening for HIV-infected patients attending the Comprehensive Care Clinic at Mbagathi District Hospital, a public district hospital in Nairobi. The clinic continues to have a functional cervical cancer screening program for its patients, using visual inspection with acetic acid/ lugol’s iodine (VIA/VILI). As an ID fellow, I later conducted a study to reduce rates of catheter-associated urinary tract infections (CAUTIs) among patients admitted to the medical wards of Mbagathi District Hospital. As a part of this study, we were able to improve infection control practices at this hospital and later published this work.

Following my infectious diseases fellowship, I was keen to continue my work in ID and global health, and thus joined the Global Health Residency/ Fellowship pathway at Duke University. As a Global Health/ Fogarty Fellow, I had the opportunity to obtain a Masters of Science in Global Health and spent a year in southern Sri Lanka conducting work on febrile illnesses, associated antibiotic use, and the growing epidemic of Gram-negative resistance. I am currently continuing my work in this program, and hope to build a career in academic, global health/ ID focusing on antimicrobial resistance and infection control in the developing setting.

Kimberly Ganster, MD

Gallup Indian Medical Center
Gallup, New Mexico

As a Global Health Equities and Primary Care Track resident I was able to spend much of my clinical time during residency at the Lax Center, one of the city’s HIV clinics; Prevention Point, a syringe exchange program; and at the refugee clinic at Penn Center for Primary Care. My international work was at Mbagathi Hospital in Nairobi, Kenya, where I helped to develop a teaching curriculum for clinical officer interns during their medicine rotation.

After completing residency in 2012, I took a position with the Botswana UPenn Partnership as a Teaching Specialist at Princess Marina Hospital in Gaborone. I attended on the inpatient wards, worked at the outpatient general medicine clinic and precepted University of Botswana medical students. I worked closely with Penn residents and med students during their two month rotations in Botswana.

After one year in Botswana, I took a position with Indian Health Services at Gallup Indian Medical Center in New Mexico. I spend half my time as a hospitalist and half my time as a primary care physician. Outside of direct clinical medicine I created a program aimed at increasing physical activity among obese diabetics, I precept physician assistant students and serve on the quality improvement committee.

The experiences I had with the global health track, both in the U.S. and internationally, have been instrumental in shaping my career as a physician. I hope to continue my career focusing on community health in resource limited settings.

Mosepele Mosepele, MD

Infectious Disease Fellow
Massachusetts General Hospital and Brigham and Women's Hospital, Boston Massachusetts

My interests in global health have been primarily on HIV clinical care, treatment and longterm outcomes plus healthcare for new immigrants to the USA. During residency, I worked locally at Philadelphia Prison Health System providing HIV care for inmates and at the Penn Center for Primary Care Refugee clinic. My international site was Princess Marina Hospital, Gaborone, Botswana, where I also provided in-patient care in the medical wards and worked on a cross-sectional study evaluating the risk for cardiovascular disease among adult HIV patients on Protease Inhibitor (PI) containing Antiretroviral Regimen (ARV) in Gaborone, Botswana.

Following residency, I will start fellowship in Infectious Disease at the combined Massachusetts General Hospital(MGH) / Brigham & Womens Hospital (BWH) where I will continue to do research in HIV associated cardiometabolic disease, especially in sub-Saharan Africa. My medium term plan is to establish a career as a clinician, clinical epidemiology researcher and educator at a medical school in sub-Saharan Africa and continue collaborative work with academic centers around the world.

Jason Vassy, MD MPH SM

Instructor of Medicine, Harvard Medical School
Boston, Massachusetts, USA

As a Global Health Track resident, I had the opportunity to serve the global community both in Philadelphia (at the Puentes de Salud clinic for Latino immigrants) and in urban and rural Guatemala. The experience strengthened my commitment to primary care and, at the same time, inspired me to seek ways to improve health at a societal level. After residency, I undertook a general medicine fellowship at Massachusetts General Hospital. During this time I practiced primary care in an urban setting with high rates of substance abuse and mental health disorders. I also began a research agenda that included the examination of whether genetic discoveries made in populations of European ancestry are applicable to more racially diverse populations. Now that fellowship is coming to a close, I've taken a position at the Boston VA, where I hope to continue my research and improve primary care at both the patient and health system levels.

Serena Roth, MD

Clinical Instructor, Montifiore Medical Center
New York City, New York, USA

I went to medical school at New York University, where I participated in and later ran The Hepatitis Project, a medical student-run clinic offering hepatitis testing and counseling to injection drug users at a syringe exchange in lower Manhattan. During my residency training in primary care internal medicine at the University of Pennsylvania, I continued my work with injection drug users by starting a drop-in medical clinic with Prevention Point, Philadelphia's major syringe exchange program, and provided HIV primary care at the Jonathan Lax HIV Treatment Center. I was honored to be selected as a member of the founding class of Penn's Global Health Track in 2008. The GHT provided me with excellent opportunities and mentoring to expand my interests in global and community health, allowing me to have multiple outside continuity clinics and work directly with faculty involved with international health projects. Having a group of dedicated, supportive, and enthusiastic residents and faculty helped me work towards my clinical and research goals despite residency's otherwise busy schedule. In the international travel time afforded by the GHT, I traveled to Bangkok for the International Harm Reduction Association conference in 2009 and to Botswana for a clinical elective in 2010.

After residency, I moved to Bangkok, Thailand for one year, where I worked as a research fellow in the Tuberculosis Division at the Centers for Disease Control. Since 2011, I have been a clinician educator at Montefiore Medical Center in the Bronx, NY. At Montefiore, I am a primary care physician to an underserved and fantastically diverse patient population, precept residents in their busy clinic, and coordinate multiple educational activities with the faculty, medical students and residents. My current focus is on management of patients with chronic pain on prescription opioids; I am a core member of a pilot study providing comprehensive medical and psychosocial care to high-risk patients on chronic opioids, and have begun prescribing buprenorphine for opioid dependence.
