Academic Philosophy

"Our Division is dedicated to the delivery and ongoing development of interdisciplinary clinical care, research and teaching programs that focus on allergic diseases, immunodeficiencies and immune dysregulation with collaborators in Florida and beyond"

Interdisciplinary and Emerging Signature Programs

  • Allergy, Immunology & Infectious Disease

Research Interests

  • Our research interest is in profound combined immunodeficiencies, such as severe combined immunodeficiency (SCID), its variants (e.g. IL2RG, ADA, RAG1/2 genes, NHEJ complex) and other genetically defined immune disorders (e.g. linked to genes such as PI3KCD/R1, CTLA4, NFKB1/2 genes). In particular, our research team investigates mechanisms of B cell dysregulation triggered by intrinsic (e.g., cytokines, transmembrane proteins) and extrinsic mechanisms (e.g., viral antigens, microbiome) in patients and mouse models of these inborn errors of immunity (IEI). Our research also extends to IEI patients presenting with autoimmune cytopenias, WHIM syndrome (warts, hypogammaglobulinemia, infections and myelokathexis), and those with COVID-19. Through collaboration, we contribute to the development of targeted therapies for IEI, including novel bone marrow transplant and gene therapy approaches, biological agents, and pharmaceuticals, with the long-range goal of improving patient care.
