Research Projects

Optimal immune responses are required to fight infections. However, if the immune responses are not regulated appropriately, they can cause inflammatory disorders. I am studying the mechanisms by which unwanted immune responses are regulated. I am focusing on how regulatory T cells (Tregs) and cytokine networks control inflammatory cells in different disease settings.
