MacGlashan to Step Down as Division Director

Dr. Donald MacGlashan will retire from his role as director of the Division of Allergy and Clinical Immunology effective July 1.

Dr. MacGlashan has expertly led the Division of Allergy and Clinical Immunology since 2016. Under his direction, the division saw the development of disease-focused centers of excellence as well as the recruitment of promising junior faculty and fellows in order to merge scientific discovery with excellent clinical care. He is a prolific investigator, and gained international recognition for his pioneering research on the biochemistry and cell biology of mast cells and basophils. After more than 40 years in the division, he will step down as director to focus on his research. We’d like to express our sincere gratitude for his leadership and dedication to the Department of Medicine.

Dr. Antoine Azar is an associate professor and has served as clinical director of the Division of Allergy and Clinical Immunology since 2015. He earned his medical degree from the American University of Beirut in Lebanon and completed an internal medicine residency and fellowship in allergy and immunology at the University of Iowa. He then served on the faculty at the University of Iowa before joining Hopkins in 2015. In 2016, he launched the Adult Primary Immunodeficiency Center of Excellence at Johns Hopkins Bayview Medical Center, which now draws patients with immunodeficiency disorders from all over the world. Dr. Azar also developed and established a system-wide penicillin allergy screening service based in the Allergy and Clinical Immunology Clinic at JHBMC. He is known to be an esteemed clinician, and has been named a Top Doctor by Baltimore Magazine several years in a row. We are both excited and grateful to Dr. Azar for accepting the position as interim director of the Division of Allergy and Clinical Immunology, and confident his leadership experience and skill in program building will bolster the division.
