Research Summary

Dr. Tormey has several diverse research interests within the fields of Transfusion Medicine & Laboratory Hematology ranging from large clinical studies to translational research projects. Areas of current investigation include blood bank-based immunohematology where the properties of red blood cell alloantibodies in veteran populations are examined, particularly those factors influencing the duration of humoral response following alloimmunization. In addition, Dr. Tormey is interested in studying the biochemical and immunologic effects of storage on platelet components in the blood bank. Finally, he is also interested in studying coagulation assays, in particular the clinical scenarios leading to discrepant coagulation test results and the general impact of coagulation assays on transfusion-related care.
