Dr. Henry Masur is well known for his expertise in the management of HIV and its comorbidities, and for his expertise in ICU-related infections. His department has published many pivotal studies related to sepsis, the safety of the blood supply, microbial diagnostics, emerging infections, and pulmonary immunology.


Dr. Masur earned his undergraduate degree from Dartmouth College and his medical degree from Cornell University Medical College. He completed his internship and residency in internal medicine at New York Hospital and Johns Hopkins Hospital. Following a fellowship at Cornell in the Division of Infectious Diseases and Internal Medicine, he served as an Instructor and Assistant Professor of Medicine in the Infectious Diseases Division at Cornell from 1978 to 1982.

He was recruited to NIH in 1982 to jointly found a new department of critical care medicine and an HIV/AIDS program with the National Institute of Allergy and Infectious Diseases. He became Chief of the Critical Care Medicine Department in 1989. The Critical Care Medicine Department manages the NIH Clinical Center’s only medical-surgical ICU, emphasizing multidisciplinary care.

CCMD has attained national and international acclaim for its leadership in areas of sepsis, HIV/AIDS, pulmonary immunology, pneumocystis pneumonia, clinical epidemiology, and emerging infections including Ebola and COVID-19. Its senior staff includes national leaders in professional societies and national clinical care guidelines and editorial leaders of major professional society journals.

The department has developed a highly competitive, highly sought training program in critical care medicine which permits candidates to train in pulmonary medicine, infectious diseases, or cardiology as a second subspecialty. The program is led by master teachers who also lead a regional training consortium that takes advantage of the best regional faculty to train ACGME fellows. Its fellowship alumni have leadership positions at academic medical centers across the U.S., as well as leadership roles in professional societies.

Dr. Masur is the founding editor of the NIH-CDC-IDSA Guidelines for Management of Opportunistic Infections in Adults and Adolescents with HIV Infections, Past President, Infectious Diseases Society of America and Senior Associate Editor of Critical Care Medicine. He is the chair of the IDSA Sepsis Task Force and Co-Chair of the NIH COVID-19 Treatment Guideline and the recipient of the 2020 HHS Hubert Humphrey Award for Service to America.

He leads the District of Columbia Partnership for AIDS Progress, a unique collaboration between NIH and the DC government which has created an urban model for decreasing the impact of HIV/AIDS on underserved populations. The program includes the largest urban cohort study of HIV/AIDS in the U.S., and did the first U.S. trials of interferon free therapy of HCV. The program has expanded its focus to new approaches to opioid use disorder with funding from the NIH Office of AIDS Research and the NIH HEAL Program.

Dr. Masur holds clinical appointments at the University of Maryland and the George Washington University School of Medicine.
