Scientific Interests

Dr. Timothy O'Sullivan's research focuses on circulating and tissue-resident innate lymphoid cell (ILC) responses during inflammation. This involves models of viral infection, diet-induced obesity, cancer immunoediting and metastasis. His lab is interested in understanding the role of tissue-resident ILC1 in cancer immunosurveillance and the mechanisms by which cancer escapes IFN-gamma mediated immune suppression.
