Dr. Raul Braylan has been interested in the pathobiology of hematologic malignancies and related disorders for many years.

Dr. Braylan received his medical degree from Buenos Aires Medical School in Argentina, and completed internship and residency in pathology at Mt. Sinai Hospital in Chicago and Albert Einstein College of Medicine in the Bronx. He was then a Senior Clinical Trainee for Cancer Control in the Pathology Department of Sloan Kettering Institute in New York and a U.S. Public Health Service Trainee in Hematopathology, and Instructor in the Department of Pathology at the University of Chicago.

He was subsequently appointed senior staff fellow in the National Cancer Institute at NIH in 1973, where he served for four years.

He then joined the Department of Pathology at the University of Florida in Gainesville, Florida, where he was the Chief of Hematopathology, Director of the Hematology course for medical students and Director of the Hematopathology Fellowship Training Program. Following his tenure at the UF, Dr. Braylan helped organize and direct the Hematopathology service at CARIS Life Sciences in Phoenix, AZ, and finally joined the Department of Laboratory Medicine in the Clinical Center at NIH in 2011.

Research Interests

Dr. Braylan has been interested in the pathobiology of hematologic malignancies and related disorders for many years. He was one of the pioneers in the clinical use of flow cytometry as a tool for diagnosis, characterization and monitoring these malignancies, and actively participated in international efforts to establish standardization in data analysis and reporting of clinical flow cytometric results.

He has mainly studied lymphoid malignancies in the past and he now focuses his efforts on myeloid and plasma cell disorders.

Among many other professional affiliations, Dr. Braylan is a member of the American Society of Hematology and the American Society of Clinical Pathologists. He has been an editorial board member of Cytometry Part B: Clinical Cytometry, and an associate editor at Laboratory Investigation.

He has published books, book chapters and more than 150 peer-reviewed articles in scientific journals.

See his Intramural Research Program bio page.
