Biography
Dr. Jan Philipp Bewersdorf is an Assistant Professor of Medicine (Hematology) at Yale University. Following medical school training in Germany, he completed his Internal Medicine training at Yale - New Haven Hospital. After completion of residency, Dr. Bewersdorf pursued his fellowship in Hematology and Medical Oncology at Memorial Sloan Kettering Cancer Center in New York before joining the faculty at Yale in July 2024. Dr. Bewersdorf is board-certified in Internal Medicine, Medical Oncology and Hematology.
His career as a clinician-scientist has been dedicated to myeloid malignancies spanning from myeloproliferative neoplasms to myelodysplastic syndromes and acute myeloid leukemia. Dr. Bewersdorf's work aims to combine basic and translational research with clinical and outcomes research to study those disorders from multiple angles. Inspired by the privilege of taking care of patients with myeloid neoplasms, he strives to advance patient care by conducting innovative clinical trials with a strong correlative component in collaboration with laboratory-based colleagues. He has developed and co-led several early phase clinical trials in myeloid malignancies and his research efforts have led to over 130 peer-reviewed publications to date including first-author publications in Lancet, Blood, Leukemia, and Lancet Haematology.
Dr. Bewersdorf has received several prestigious awards including the Edwards P. Evans Young Investigator Award, the Mortimer Lacher Fellowship from the Lymphoma Foundation, and multiple other achievement awards. He also serves on the editorial board and is a reviewer of several important hematology and oncology journals.
