Current Research Interests:

Infection by pathogens that range from parasites to bacteria elicits vigorous antibody responses critical for host protection. It is clear that optimal humoral immune responses depend on T follicular helper (TFH) cells and follicular dendritic cells (FDCs), which are subsets of immune cells that form direct, or cognate, interactions with B cells in secondary lymphoid organs to promote germinal center formation, isotype class-switching, and affinity maturation of the B cell receptor. While these two cell types have recently been well characterized, there remains a dearth of knowledge about the factors produced by TFH and FDCs that imprint organ specific trafficking on plasma cells, as well as memory and effector B cells. The overall focus of my research program uses the models I developed during my postdoctoral studies in B cell and TFH cell biology in response to the parasitic helminth Schistosoma mansoni, which chronically infects ~200 million people worldwide, to define the mechanisms of organ/lymphoid specific B cell trafficking in response to multiple infectious and protein based stimuli. I have two currently funded projects available to students.Project 1. Investigating the mechanism of Liver B cell priming and recruitment during chronic Schistosoma mansoni infection. This project uses multiple knockout and reporter mouse strains combined with microarrays to define a transcriptional and chemokine/cytokine signature that imprints tissue specific homing onto memory and effector B cells during the course of S. mansoni infection.Project 2. Development of a novel pathology reducing S. mansoni specific vaccine. This project aims to develop a subcutaneous vaccination strategy that leads to the early development of the protective S. mansoni specific liver plasma cell compartment, and the early immunomodulation of the granulomatous reaction to eggs.
