Assistant Chiefs of Service (ACS)

  • Robbie Flick, MD, Janeway Firm

    Robbie grew up in Baltimore County and went to Union College for undergrad and University of Colorado for medical school. Along the way, he spent a few years in Malawi where he did tuberculosis research and met his wife, Ruth. He came to Hopkins as a resident for the camaraderie among the house staff and the commitment to patient care demonstrated by everyone he interacted with on his interview day. Robbie finished his first year of Pulmonary and Critical Care Medicine training at Hopkins, and his interests include tuberculosis and pulmonary infections in the ICU. Outside of the hospital, you’ll find him mountain biking along the gunpowder, hiking with Ruth, grooming his mustache or hanging out with one of his family’s corgis.

  • Angela Ma, MD, Barker Firm

    Angela grew up in Carmel, IN. She attended MIT for college and completed medical school at Johns Hopkins. She was a Thayer resident, but is now proud and honored to be the Barker ACS. She completed her first year of pulmonary and critical care fellowship at MGH/BIDMC in Boston (and survived the winter with the assistance of a floor-length parka, for which she was heckled for mercilessly by her colleagues) prior to returning to Baltimore for ACS year. She is excited to return to the Osler Medical Residency due to the residents' clinical excellence, strong commitment to patient care and close relationships with and support of one another. Outside the hospital, Angela enjoys listening to podcasts and classical music, cooking and desperately trying to keep her collection of houseplants (+one tomato plant) alive.

  • Andi Shahu, MD, Thayer Firm

    Andi was born in Tirana, Albania but grew up in Washington, D.C. He completed his undergraduate degree at Johns Hopkins University and medical school at the Yale School School of Medicine. He decided to return to Baltimore for residency because of the Osler program’s commitment to clinical excellence and education through the lens of the unique Firm structure. Andi returned to New Haven and completed his first year of his Cardiology fellowship at Yale-New Haven Hospital prior to returning to Baltimore for ACS year. As an ACS, he is most excited to mentor and learn from the incredible Osler residents. From a clinical and research perspective, he is interested in general cardiology, cardiovascular critical care, echocardiography, as well as the intersection between cardiovascular outcomes, health equity and health policy. His hobbies include running, writing, music, traveling and spending time with family and friends.
