    Professor
    Vaccines


    Research Interests -

    HIV Research - I have been working with HIV in Africa since the first recognition of the epidemic on that continent in 1985. My initial work was focused on the epidemiology, natural history, and manifestations of HIV infection in African men and women. Building on previous work, this grew to include collaborative studies of the virologic, immunologic, and immunogenetic correlates of transmission from men to women and women to men. In addition to the observational studies, I have also worked on development and testing of HIV prevention strategies including behavioral (couples; HIV testing, combined prevention of HIV and unplanned pregnancy) and biomedical interventions (HIV vaccine candidates, vaginal microbicides, acyclovir). Recently, I have added a translational aspect to the work, with an emphasis on implementation of evidence-based prevention programs in the public health sector.

    Kyle T. Bradley, MD


    Assistant Professor
    Hematopathology


    Clinical Focus -

    My clinical service work is primarily focused on diagnostic hematopathology at Emory University Hospital, which includes signout of bone marrow, blood, spleen, lymph node, and extranodal hematopoietic specimens, as well as signout of flow cytometry and routine cytogenetic studies. I also provide consultative hematopathology services for external client pathologists. My clinical interests are in benign lymphoproliferative disorders such as HIV lymphadenitis, Castleman disease, and IgG4-related disease. Review of hematopathology/flow cytometry case material is performed concurrently with teaching of hematopathology fellows and residents rotating through the hematopathology service. In addition, I instruct Emory medical students and students in the Emory Medical Technology program.

    Research Interests -

    - My research interests are primarily focused on pathology education and improving communication in the fields of hematopathology and surgical pathology, with an emphasis on improved cancer reporting. Other research activities include investigations into the diagnosis and pathogenesis of IgG4-related disease, and applications of ancillary studies, particularly immunophenotyping, in the diagnosis of benign and neoplastic lymphoproliferative disorders.

    Professor
    HLA and Transplantation


    Clinical Focus -

    I co-direct, along with Dr. Howard Gebel, the busy HLA laboratory at Emory University Hospital, which provides histocompatibility testing to support transplantation services at Emory Healthcare and beyond.

    Research Interests -

    Overview - - The thrust of my research has been almost exclusively applied. Since my training and clinical responsibilities encompass two quite distinct entities, my research has also moved in several directions. However, an underlying theme has been the application of "State-of-the-Art" technology, specifically Flow Cytometry, to advances in diagnostic testing. In the area of transplantation, my projects have focused on the flow cytometric crossmatch and flow cytometric detection of alloantibody in patients awaiting transplantation. Our research efforts have essentially helped "set the standard of practice" for flow cytometric crossmatching and antibody identification in the United States. Additionally, we were one of the first laboratories to pioneer the area of microbead technology and its applications in clinical histocompatibility testing. Work that has been published from this laboratory has not only changed laboratory practice, but has been the foundation for changes in government (CLIA) and society (ASHI and UNOS) standards which regulate histocompatibility testing laboratories. In the area of clinical diagnostic flow cytometry, we have focused on cutting-edge applied projects. Our work has been primarily aimed at the utility of cytometry in the detection and classification of hematopoietic disease. To this end, our laboratory has been one of the leaders in flow cytometric analysis, an interpretation of leukemia/ lymphoma immunophenotyping. Of special interest have Read more...

    Hemostasis and Coagulation


    Clinical Focus -

    Thrombophilia and Congenital & Acquired

    Hemostasis- Complications of Pregnancy & Reproduction

    Research Interests -

    Hemostasis - Complications of Pregnancy & Reproduction Dr. Duncan and his staff have identified several profiles that identify patients at higher risk for problems and in particular have recognized that a particular analyte Lipoprotein (a) has a much higher frequency in this population and may be an important predictor of future pregnancy problems. As a result of this work on infertility patients he has devised a protocol now used by all major IVF groups in Atlanta in which LMW heparin is started prior to embryo transfer and this has apparently improved the pregnancy success rate. He believes the whole infertility and early pregnancy failure area offers significant opportunity for further study on the involvement of the hemostasis system in diagnosis and monitoring of these patients in the first trimester.

    Clinical Pathology


    Clinical Focus -

    Dr. Ross Fasano is an Assistant Professor of Pathology and Laboratory Medicine and Pediatric Hematology/Oncology at Emory University School of Medicine. He also has an adjunct appointment in Adult Hematology and provides comprehensive care to adult patients with sickle cell disease at Grady Memorial Hospital. His clinical expertise is in pediatric transfusion and hematology, with an emphasis on chronic transfusion therapy for children and adults with sickle cell disease. He is trained in Pediatrics, Pediatric Hematology/Oncology, and Blood Banking/Transfusion Medicine. He is the Assistant Director of the transfusion service and Director of Apheresis at Children's Healthcare of Atlanta. During his training and subsequent practice of medicine, he has had extensive clinical experience in managing heavily alloimmunized and iron overloaded patients with sickle cell disease.

    Research Interests -

    Red blood cell alloimmunization - Dr. Fasano and his group are interested in understanding the immunologic mechanisms involved in RBC alloimmunization in patients with sickle cell disease (SCD). In collaboration with other investigators, Dr. Fasano has demonstrated a direct role of recipient inflammation on alloimmunization, and continues to investigate immunologic mechanisms involved in alloimmunization. Conceived from murine model data illustrating that transfusion in the presence of pro-inflammatory signals results in higher rates and magnitude of alloimmunization, his group published a large retrospective study in a large human SCD cohort demonstrating that that recipient pro-inflammatory state, most notably acute chest syndrome (ACS) at the time of transfusion, directly impacts RBC alloimmunization. In collaboration with other investigators at Emory, he is currently conducting two follow up translational research studies evaluating immunologic mechanisms involved in RBC alloimmunization overall, and specifically why the frequency is highest during SCD patients during ACS.

    Jeannette Guarner, MD


    Professor
    Infectious Disease Pathology


    Research Interests -

    Helicobacter pylori infections in children and adults. - When I was working at the National Cancer Institute in Mexico, I started studying the acute and chronic effects of Helicobacter pylori infection in adults. Together with Stanford University and a group in Chiapas State in Mexico, we did a case control trial to see if eradiaction of H. pylori decreased the amount of preneoplastic lesions. My interest has expanded to the study of this infection in children and I am currently involved in several projects in this population.

    Emerging and Re-emerging infections - Upon arriving at the Centers for Disease Control and Prevention (CDC), I was integrally involved in high-prorfile outbreak investigations of emerging and re-emerging infectious diseases. The CDC pathology team has developed a variety of immunohistochemical and molecular assays to detect these patholgens. Detection of microbial antigens by immunohsitochemical methos in tissues has to be correlated with other laboratory tests. The combination of tissue and laboratory diagnosis of infectious agents is of vital importance to detect these emerging and re-emerging infections so that public health authorities place control and prevention measures.

My clinical focus encompasses use of morphologic analysis, flow cytometric immunophenotyping, molecular diagnostic and fluorescence in situ hybridization/cytogenetics studies that are relevant to the subspecialty of hematopathology.

    Research Interests -

    Inflammation/ Hematopathology - I have 2 areas of ongoing investigation. One focus is a C-type lectin-family receptor (CD303) expressed uniquely on the surface of human plasmacytoid dendritic cells. Data suggest that this receptor impacts function of these cells in innate and adaptive immunity. We have developed unique biochemical tools to better understand the structure and function of CD303 including identification of natural binding targets whether of self or non-self origin. Specific efforts focus on identifying the specific counter-receptors on these targets and better characterizing the impact of receptor-ligand engagement. A second focus involves deciphering the role of the Bcl-6 interacting transcriptional co-repressor MTA3 and BCL6 in B cell lymphomas, work done in collaboration with Dr. P. Wade at NIEHS, and translating this knowledge into diagnostically useful tools.

    Hematopathology
    Molecular Genetic Pathology


    Clinical Focus -

    I serve as an attending physician on the Hematopathology and Molecular Diagnostic Laboratory service at Emory University Hospital. My clinical focus includes diagnostic hematopathology integrating morphologic examination, flow cytometric immunophenotyping, cytogenetics, FISH, and microarray studies; and molecular diagnosis of solid tumors.

    Research Interests -

    Genetic profiling of hematologic malignancies and solid tumors - It is now widely accepted that cancer is a genetic disorder. Whole genome profiling of human cancer, as well as genetic analysis by re-sequencing panels of genes associated with specific malignancies have not only become a major research tool of discovering new genetic abnormalities associated with individual disease and patient, but also been gradually adapted as routine diagnostic tests in clinical molecular laboratories. Hematopathology has been traditionally, and continued to be the leading field in novel research and discovery of clinically significant genetic abnormalities. I am interested in the genetic profiling of hematologic malignancies including myeloid neoplasms, lymphomas, multiple myeloma, and solid tumors, especially lung cancer and melanoma, using high resolution microarray, RNA-seq, and panel gene sequencing, aiming at bringing these into clinical laboratory as routine diagnostic tests.
