Stephen Oh, MD, PhD is Associate Professor of Medicine in the Division of Hematology at Washington University School of Medicine. Dr. Oh’s clinical and laboratory research efforts are focused on myeloproliferative neoplasms (MPNs). His group employs patient samples and animal models to investigate fundamental mechanisms driving the initiation, development, and progression of MPNs. A major focus of the laboratory is to utilize mass cytometry and multiplex imaging approaches to interrogate dysregulated cytokine signaling networks in MPNs. Dr. Oh has extensive clinical experience in the diagnosis and management of MPN patients and has contributed to numerous clinical trials investigating novel targeted therapies for MPN patients. The long-term objective of his work is to translate the findings from his laboratory research into improved therapies for MPN patients.
