    Dr. Di Stasi received his M.D. degree from the University of Modena in Italy. He did his internal medicine and medical oncology training at the university of Milan, in Italy, where he trained in particular in the management of hematologic malignancies and hematopoietic stem cell transplantation. Following his fellowship he joined the Center for Cell and Gene Therapy (Baylor College of Medicine, Houston, TX) for post-doctoral studies, where he completed the pre-clinical validation of an immunotherapy protocol for the treatment of relapsed Hodgkin lymphoma, and the clinical validation of a novel suicide gene safety switch for graft-versus-host-disease occuring after donor lymphocyte infusion. Afterwards, he underwent ECFMG certification and moved to the University of Texas MD Anderson Cancer Center for Bone Marrow Transplantation fellowship and clinical research, especially regarding myelodisplastic syndromes, acute myeloid leukemia, and haploidentical hematopoietic stem cell transplantation.

    His work has been published in high-impact journals such as Blood, and The New England Journal of Medicine. In addition, he has authored four book chapters and has lectured in the US and Europe.

    Research Interests:
    Dr. Davis' laboratory is focused on the cellular and molecular immunobiology of lymphocytes in normal and diseased conditions. He has been broadly trained as a physician-scientist with a background in basic lymphocyte development and receptor biology. As a postdoctoral fellow he co-discovered a multigene family that encodes Fc receptor-like (FCRL) molecules with tyrosine-based regulatory potential that are expressed by subpopulations of lymphocytes in normal and diseased states. Current work involves investigating FCRL members in humans and mice to define their functional roles in normal and aberrant immune conditions. Work by his group and through productive collaborations has provided a better understanding of these receptors in basic immunology as well as in clinically important autoimmune and malignant conditions. Beyond his role as a physician-scientist, he also serves as Director of the UAB Multidisciplinary Molecular Interaction (MMIC) Core Facilitywhich supports the operation of a Biacore T200 instrument. This technology allows for the determination of very sensitive kinetic interactions between macromolecules and/or small drugs using surface plasmon resonance (SPR).

    Major Research Interests

    My research goals are to develop an improved understanding of abnormal regulation of malignant stem and progenitor cells in hematologic malignancies and to develop effective approaches to eliminate these cells to enhance outcomes for these cancers. In addition to being a practicing clinical Hematologist-Oncologist and Hematopoietic Cell Transplant physician, I have extensive experience in studying normal and malignant hematopoietic stem cell regulation in the translational laboratory setting. During my fellowship at the University of Minnesota, under the mentorship of Dr. Catherine Verfaillie and Dr. Philip McGlave, I studied mechanisms of microenvironmental regulation of normal and malignant hematopoiesis, and mechanisms of response and resistance of leukemia stem cells to therapy. After establishing my independent research program at City of Hope, I have continued to investigate mechanisms of regulation of normal and leukemia stem cell growth and therapeutic targeting of leukemia stem cells. My research goals are to develop an improved understanding of abnormal regulation of malignant stem and progenitor cells in hematologic malignancies and to develop effective approaches to eliminate these cells to enhance outcomes for these cancers. I was appointed as Director of the Division of Hematopoietic Stem Cell and Leukemia Research and co-Director of the Hematological Malignancies Program in the Comprehensive Cancer Center in 2006 to develop a basic and translational program in hematological malignancies and hematopoietic stem cells at our center. Since taking over this position, I have recruited and mentored an outstanding group of young faculty with a common interest in investigating mechanisms of regulation of normal stem cell growth; cellular and molecular mechanisms underlying hematopoietic cell transformation in patients with hematological malignancies; identification of critical therapeutic targets; and preclinical and clinical development of innovative, mechanism-based therapeutic interventions.
