Clinical Care

Overview

Daniel Boxer, MD, is a hematologist who specializes in the diagnosis and treatment of both benign (non-cancerous) and malignant (cancerous) blood disorders. He cares for patients with a wide range of conditions, including clotting and bleeding disorders, various types of anemia (low red blood cell count), platelet and white blood cell disorders, complications related to pregnancy and blood, iron-related conditions, inherited blood diseases, myeloproliferative neoplasms (conditions where bone marrow produces too many blood cells), myelodysplasia (disorders caused by poor-functioning bone marrow), leukemias, lymphomas, and plasma cell disorders.

As an assistant professor of medicine at Yale School of Medicine, Dr. Boxer’s academic work has focused on paroxysmal nocturnal hemoglobinuria, an uncommon blood disease that affects red blood cells and can cause problems such as abnormal blood clotting. His research explores why people with this condition may have an increased tendency to form blood clots, looking specifically at how abnormal platelets contribute to this risk. In addition to his research, Dr. Boxer is committed to medical education and has received several teaching awards for his work with trainees.

Dr. Boxer received his medical training at St. George’s University, completed his residency at Georgetown University Hospital, and pursued a fellowship in hematology and medical oncology at New York University.
