  Immunology & Pathology

  Autoimmunity

  Lupus Pathogenesis

  Dr. Morel’s research program investigates the mechanisms of lupus pathogenesis using mouse models as well as patient samples, with a focus on CD4 T cells and B cells. The long-term goal of her research is to identify genes or pathways responsible for lupus susceptibility, to characterize their contribution to autoimmune immunopathology, and to translate these findings into therapeutic targets. The most recent work has explored recent work on the genetic, cellular, metabolic and microbial determinants of follicular helper T cell expansion and regulatory T cell impairment in lupus.
