    Alexandra (Lisa) H. Filipovich, MD Ralph J. Stolle Chair, Clinical Immunology

    is a clinical immunologist who studies the genetics and pathogenesis of congenital immunodeficiencies including HLH (hemophagocytic lymphohistiocytosis). Translational research involves developing safer approaches to hematopoietic cell transplantation for such diseases, as well as the application of gene therapy.

    Michael S. Grimley, MD

    has clinical research interests in the treatment of Graft versus Host Disease (GVHD) after transplant and the use of umbilical cord blood as a stem cell source.

    Michael B. Jordan, MD

    specializes in caring for children with histiocytic disorders, primary immune deficiencies, or who are undergoing bone marrow transplantation. His laboratory focuses on understanding effector T cell function, immune regulation, and the pathogenesis of hemophagocytic lymphohistiocytosis. He is also conducting preclinical scientific studies in addition to a translational clinical trial.

    Ashish R. Kumar, MD, PhD

    is a pediatric hematologist-oncologist who has a research program investigating the biology of leukemia caused by MLL-fusion genes. These leukemias are most common in infants and frequently fatal. The research in Dr. Kumar's lab is focused at identifying downstream targets of MLL-fusion proteins that could be exploited to develop novel therapies. Currently, the Kumar lab is investigating the role of MEIS1 in MLL-leukemia.

    Rebecca A. Marsh, MD

    is an immunologist and bone marrow transplant physician. Her research focuses on understanding the pathogenesis of HLH in patients with XIAP deficiency, developing new diagnostic laboratory assays, and improving the outcomes of allogeneic bone marrow transplantation in patients with primary immune deficiencies.

    Kasiani C. Myers, MD

    is a bone marrow transplant physician focused on translational research in bone marrow failure and Fanconi anemia (FA), specifically the longitudinal evaluation of hematopoiesis in FA as a model for de novo leukemogenesis. These studies will lead to development and clinical trials of targeted therapies to preserve stem cell function through the elucidation of the steps in the pathway towards marrow failure and malignant transformation.

    Kimberly A. Risma, MD, PhD Director, Allergy and Immunology Fellowship Program

    is focused on the molecular and cellular bases of primary disorders of immune deficiency and dysregulation, especially as it relates to lymphocyte cytotoxicity. She studies the pathologic consequences of missense mutations in perforin identified in patients with hemophagocytic lymphohistiocytosis (HLH) and strives to develop novel therapies through gene therapy or small molecule chaperones.

    Janos Sumegi, MD, PhD

    is a molecular geneticist who has an interest in the molecular mechanisms involved in Familial Hemophagocytic Lymphohistiocytosis and X-linked Lymphoproliferative Syndrome. A second focus of his lab is to study the genes and regulatory pathways involved in the tumorigenesis of alveolar rhabdomyosarcoma.
