Ronald Hoffman, MD, is the Albert A. and Vera G. List Professor of Medicine, Professor of Medicine (Hematology and Medical Oncology), and Director of the Myeloproliferative Disorders Research Program. He founded this program in 2007 and has developed it into one of the most effective and well respected programs in the world dealing with myeloproliferative disorders. His interest in this group of blood cancers stemmed from his time as a fellow in Hematology at Mount Sinai (1974-1977.), where he worked with numerous Mount Sinai faculty including Drs. Ralph Zalusky, Esmail Zanjani, and Lewis Wasserman. After holding administrative positions at several other institutions, Dr. Hoffman retuned to Mount Sinai in 2007 to work in the laboratory and the clinics in order to focus on translational research in blood cancers. He continues to care for patients with myeloproliferative neoplasms on a daily basis.

Dr. Hoffman is a leader in stem cell research. His studies of human hematopoietic stem cells and progenitor cells in myeloproliferative neoplasms have led to many therapeutic advances. He has also pioneered a unique method of increasing the number of cord blood stem cells used to treat patients with blood cancers and blood disorders.

In 2003, Dr. Hoffman founded the Myeloproliferative Neoplasm Research Consortium, a multi-institutional program project grant funded by the National Cancer Institute, which is committed to research in and treatment of myeloproliferative neoplasms. The Consortium involves 12 institutions throughout the United States and Canada and is focused on identifying new therapies for patients with myeloproliferative neoplasms and evaluating their effectiveness in carefully constructed clinical trials

Dr. Hoffman has served as president of the American Society of Hematology and the International Society for Experimental Hematology.

Dr. Hoffman is the editor of Hematology: Basic Principles and Practice. He conceptualized and organized this leading textbook of hematology, which is currently entering its eighth edition. He is an author on almost 500 peer-reviewed publications and 130 books/book chapters/reviews. He has also served as the editor of the journal Experimental Hematology.

Dr. Hoffman has mentored countless post-doctoral fellows and junior faculty, and serves as advisor to the Mentoring Committee for junior faculty at the Icahn School of Medicine at Mount Sinai.

In 2017 Dr. Hoffman received the prestigious Mentor Award from American Society of Hematology in recognition of his outstanding commitment to the training and career development of early-career hematologists and advancing research and patient care in hematology.
