Research/Clinical Interest
The developmental immunology of lymphocytes and immunoreceptor biology. Lymphoproliferative disorders and mechanisms that contribute to lymphomagenesis and autoimmunity.
Dr. Davisí 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. His clinical expertise is in Hematology/Oncology with a specific focus on B cell chronic lymphocytic leukemia (CLL) and lymphoproliferative disorders. As a postdoctoral fellow he co-discovered a multigene family termed FCRL that encodes 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. Studies by his group and through productive collaborations have provided a better understanding of the role of these receptors in basic immunology as well as in clinically important autoimmune and malignant conditions. Dr. Davis also directs the Multidisciplinary Molecular Interaction Core (MMIC). This facility supports the operation of a Biacore T200 instrument which enables sensitive determinations of interactions between biomolecules using surface plasmon resonance (SPR) technology.
