Director, Division of Transfusion Medicine
Primary Appointment in Pathology; Secondary Appointments in Medicine, Oncology

Our laboratory has a long standing interest in development of assays for detecting red cell antibodies and small populations of heterogeneous red cells using a quantitative enzyme-linked antiglobulin test. This assay has proved useful in the study of fetal-maternal hemorrhage, red cell survival studies, and autoimmune hemolytic anemia. We are also studying Rh immunization in pregnancy taking advantage of molecular testing methods for blood grouping. Ongoing clinical studies in transfusion medicine include the use of blood components in trauma and cardiac surgery, the effects of the age of stored red cells and methods to reduce these defects, clinical investigations of pathogen reduced blood components, multiple studies on transfusion reduction in patient blood management settings, the development and use of hemoglobin-based oxygen carriers as blood substitutes, and several projects on international blood safety including HIV and hepatitis reduction and blood utilization patterns in China.
