  • PhD, The University of Iowa
  • Postdoc, Dartmouth Medical School

Primary Appointment

  • Associate Professor, Microbiology, Immunology, and Cancer Biology


Research Interest(s)

Cellular and molecular mechanisms of B lymphocyte function; Genetic susceptibility in systemic lupus erythematosus; Immunotherapeutics in the treatment of B cell disorders

Research Description


- Using mouse genetics to identify the susceptibility factors that control B cell tolerance, differentiation and survival, leading to autoantibody production.

- Defining the mechanisms by which autoimmune susceptibility elicits inflammation and recruitment of innate immune cells in secondary lymphoid organs that affect B cell function.

- Examining helper activity and inflammatory cytokines of human T cells in peripheral blood of SLE patients that affect B cell function.

- Characterizing the regulation and activity in primary mouse T follicular helper cells and T follicular regulatory cells to control B cell responses.

- Defining the signal transduction events through the BCMA cytokine receptor that regulates both T follicular helper cell homeostasis and plasma cell survival in autoimmunity.

- Characterizing the development and persistence of IgE antibodies to airway allergens.
