Ian Parish is an immunologist with an ongoing interest in the molecular control of T cell differentiation. He completed his PhD at the WEHI, during which he studied the cellular and molecular regulation of peripheral T cell tolerance. He then took up a postdoctoral position at the Yale School of Medicine, where he focused on the regulation of T cell differentiation during infection, and developed an interest in why T cell responses become blunted during chronic viral infection. After returning to Australia, he subsequently established independent research directions at the ANU that aimed to more broadly decipher the molecular pathways that limit T cell function. He joined the Cancer Cell Death laboratory in 2018 to continue and expand these projects, with the goal of using these findings to refine cancer immunotherapy approaches.
