Dr. Haigis is an active member of the Dana Farber/Harvard Cancer Center, an Affiliate of the Broad Institute, a member of the Ludwig Center at Harvard Medical School. Dr. Haigis has made fundamental contributions to our understanding of how mitochondria contribute to human health and diseases of aging. Her pioneering studies identified ways that mitochondria utilize fuels and signal in to support cell proliferation, pivotal in immune cell activation. Research in the Haigis laboratory has also led to a deeper appreciation and mechanistic understanding of how metabolites in the tumor microenvironment regulate T cell effector functions. Most recently, her work has shed light on our understanding of how diet, age, and obesity regulate anti-tumor immunity.
