Clíona Ní Cheallaigh is an infectious diseases and internal medicine physician in St. James’s Hospital, Dublin, and Assistant Professor in Medical Gerontology. She brings to GBHI clinical and research expertise in social determinants of health, health equity, implementation, and chronic inflammation.“Coupling our clinical experience with GBHI provides an opportunity to understand and address the link between social exclusion and brain health.” Ní Cheallaigh’s clinical and research interests center on the health of excluded individuals: homeless people, injecting drug users, and other marginalized groups. She has established an inclusion medicine service within St. James’s Hospital to provide integrated, active case management-based care to these individuals in the hospital and in outreach clinics to addiction services. Her research seeks to look at the effect of the extreme psychosocial stress experienced by excluded individuals on three levels: the cellular/immune activating consequences of this stress, the effect of this stress on health, particularly frailty and brain health, and on health services adaptation to meet the needs of this population. Her cellular biology work is informed by her doctorate studies in the Department of Immunology at Trinity College Dublin, culminating in the Immunity publication of findings on a novel role for the signaling adaptor protein, mal. Her immunological interests lie within innate immunity – particularly autophagy – and with examining the mechanisms through which psychosocial stress causes immune activation and through which low-grade chronic inflammation affects brain health and aging

At GBHI, Ní Cheallaigh provides fellows and scholars the opportunity to see the dramatic effects of socioeconomic deprivation and psychosocial stress on brain health, as well as the challenges associated with ensuring that medical advances reach marginalized groups.
