Biography
Benjamin Mba, MBBS, MRCP (UK), CHCQM, FACP, professor of medicine (general medicine), is the vice chair of diversity, equity, and inclusion for Yale School of Medicine’s Department of Internal Medicine, the graduate medical education (GME) director for diversity, equity, and inclusion and associate designated institutional official for Yale New Haven Hospital and Yale School of Medicine (YSM). Dr. Mba, a passionate advocate for diversity, equity, and inclusion, joined the YSM and YNHH on July 1, 2023, bringing a deep commitment to these principles.
Since joining Yale, Dr. Mba has instituted new educational, recruiting, and training opportunities and resources and administered the first department-wide inclusion climate survey.
Dr. Mba leads all YSM and YNHH GME outreach and recruitment efforts, driving the diversification of Yale's healthcare workforce and developing strategies for the Department of Medicine to recruit, retain, support, and ensure mentorship and sponsorship equity for under-represented in medicine (URiM) faculty.
Dr. Mba and his team created the DEI productivity calculator, an online tool for faculty that captures all DEI efforts and generates a DEI activity impact score that can enhance academic promotion evaluations at academic medical centers. He is calibrating the score as part of a nationwide study.
Before joining Yale, Mba was the associate chair of medicine for faculty development for the Department of Medicine, Cook County Health, and a professor of medicine at RUSH Medical College in Chicago. He worked at Cook County Health for 24 years.
Dr. Mba’s career has been marked by a broad focus, spanning clinical education, diversity, equity, and inclusion advocacy in graduate medical education, residency program leadership, faculty development, quality improvement, and patient safety.
Dr. Mba received several accolades from Cook County Health (CCH) and RUSH Medical College for his clinician-educator and mentor roles. Dr. Mba is a four-time recipient of the Sir William Osler Award for teaching of internal medicine from the Department of Medicine at Cook County Health (CCH), a four-time recipient of the CCH Division of Hospital Medicine’s Cooker Award for inpatient medicine teaching and team leadership, and a four-time recipient of the CCH Department of Medicine Excellence in Medical Student Education Award, a two-time recipient of the Clinical Skills and Scholarship Award as a medicine resident.
Dr. Mba was recognized as an exemplary teaching attending physician in a national research study by the University of Michigan. This exploratory qualitative study identified and studied 12 exemplary teaching physicians nationwide. The findings were published in a book titled Teaching Inpatient Medicine by the Oxford University Press and in several peer-reviewed journals, including the American Journal of Medicine and the Journal of Hospital Medicine.
Dr. Mba has given talks and presented workshops on clinical reasoning at regional and national meetings of the Society of Hospital Medicine and the American College of Physicians. He has been an invited speaker to deliver grand rounds and faculty development workshops at various teaching institutions nationwide. Dr. Mba has been a blinded discussant on Clinical Care Conundrums published in the Journal of Hospital Medicine. He was invited by the American College of Physicians (ACP) to give a national webinar on “Resident Well-being during the COVID-19 Pandemic.” Dr. Mba received a National ACP Certificate of Appreciation for National Mentoring Month.
In 2023, the Cook County Health Department of Medicine created the Dr. Benjamin I. Mba Award for Teaching Internal Medicine to honor his dedication and excellence in clinical teaching.
Dr. Mba graduated from the College of Medicine of the University of Lagos, Nigeria. He completed internal medicine residency training in the United Kingdom, obtaining the designation (MRCP (UK) via examination. He completed a second IM residency program and served as Chief Medicine Resident at the Cook County Hospital.
Dr. Mba practices as a hospitalist (inpatient medicine) at YNHH.
