Zimetbaum Fellows
Marcos "Gomez" Ambriz
2025-2026
Gomez is a fourth-year medical student at the Lewis Katz School of Medicine at Temple University, St. Luke's Campus. As the first in his family to graduate from high school and college - and now on track to become the first physician - he carries a deep commitment to understanding and improving the healthcare systems that shaped his upbringing. As an aspiring surgeon, he is eager to be at the forefront of health policy research, particularly work that examines how access to programs like Medicare and Medicaid affects the quality of care and outcomes for low-income surgical and non-surgical patients.
Azzie Boyd, MS 
2024 - 2025
A native of Boston and raised in Brockton, Massachusetts, Azariah became aware of structural change through early childhood adversities. As an aspiring physician-scientist, she envisions serving her community by bridging the realms of public health and medicine, with a focus on advancing health justice. Azariah looks forward to expanding her analytic and methodologic skillsets, gaining insights into the embodiment of socio-environmental factors, and effective solution for addressing health disparities. Since completing her fellowship, she has gone on to work for the Office of the New York State Comptroller as a Senior Health Policy Analyst.
Chantal Henry, MD
2022 - 2023
Chantal joined us as a medical student from Meharry Medical School. As a fellow, she worked under Dr. Wadhera to research cardiovascular mortality in younger adults, a population that is often overlooked. She led multiple analyses on rates of cardiovascular hospitalization and mortality, finding an alarming increase in CV hospitalizations among young adults and no narrowing of health disparities between low- and higher-income adults from 2008-2019. She presented her findings at the American Heart Association’s Scientific Sessions and published a first-author manuscript in European Heart Journal. Since graduating medical school, she is completing her residency in emergency medicine.
Ashley Kyalwazi, MD, MPP
2021-2022 Zimetbaum Fellow
Ashley was our inaugural Zimetbaum Fellow, joining us as a medical student from Harvard Medical School. With Dr. Wadhera’s mentorship and intensive training in biostatistics and epidemiology, Ashley led one of the first national analyses to investigate cardiovascular health shifts among Black and white women over the past 20 years in the US, looking at factors such as geography, rurality, and neighborhood disadvantage. She has shared her work at the American Heart Association’s Scientific Sessions, and has been published as a first-author in Circulation, where she did an accompanying interview in the Circulation podcast Circulation on the Run. Ashley has since completed a Master in Public Policy from Harvard Kennedy School and is now an internal medicine resident.
