Biographical Sketch 
I received my M.D. degree from the Federal University of Rio Grande do Sul in Brazil, followed by residency in Internal Medicine at the same institution. I moved to the United States with my husband in 1986 to become a Research Fellow at the National Institutes of Health in Bethesda, Maryland, for 2 years. We then moved to Boston, where I continued working as a fellow at Harvard Medical School. In 1993, we relocated to Birmingham, Alabama. I completed a residency in Pathology and a fellowship in Hematopathology at UAB and am Board certified in Anatomic and Clinical Pathology, with subspecialties in Hematology and Transfusion Medicine/Blood Banking. I am currently an Associate Professor of Pathology at UAB, serving as Head for Hemostasis and Transfusion Medicine sections. In addition, I am Laboratory Director of the Immunocytopenia, Anesthesia and CICU laboratories. My main focus is patient care, teaching and administrative oversight of these laboratories. In the clinical arena, I am particularly interested in improving appropriateness of utilization and interpretation of laboratory tests used in the investigation and management of bleeding and thrombotic disorders. Along with the technologists staffing the Hemostasis laboratory, we provide clinical consultation as the UAB Coagulation Service ( Since last year, I am developing a blood management program at UAB along with the Blood Utilization and Management Committee and many other colleagues from across the institution.

Research/Clinical Interest
I am interested in various aspects of clinical research in the fields of coagulation and transfusion medicine. Since UAB is a center of reference for apheresis, we receive patients from throughout Alabama and neighboring states to be treated here for thrombotic thrombocytopenic purpura (TTP). In the last several years, I have been involved in several projects about TTP as seen in my list of publications. Other areas of interest in Transfusion Medicine include the effect of storage time on the red blood cells and the repercussion for the patients, as well as transfusion-related acute lung injury (TRALI). In the area of coagulation, I have an interest in hypercoagulability, heparin-induced thrombocytopenia diagnosis, and cost-effective utilization of laboratory assays.
