A major focus in my lab is the investigation of the functional brain organization that supports human cognition and consciousness, and how this organization breaks down in the disordered brain. My work combines psychological theory, neuroimaging, and research of brain-injured and anesthesized patients, and translates this knowledge to develop clinically applicable neuroimaging measures. Additionally, my work explores the medico-ethical and societal implications of such applications, to build ethical guidelines for their clinical use.
A second focus is the investigation of early biomarkers of Alzheimer’s disease by combining neuroimaging, clinical, neuropsychological and physiological assessments. In the face of a global dementia pandemic, it is extremely important to understand the nature of the earliest cognitive/functional changes, as well as their biological basis. This can lead to better diagnoses, potential targets for treatment, and better understanding of the disease itself. We carry out this work in collaboration with the PREVENT UK project.

Dr. Naci and colleagues were awarded the Global Brain Health Institute Project Grant to change the dementia narratives and associated stigma through art and creative processes (June 2018).
Dr. Naci speaks with Bob McDonald of Canada’s Quirks and Quarks about using narratives to understand human conscious experience in non-responsive patients thought to unconscious, whether in a vegetative state, a coma, or those waking up under general anesthesia during surgery, and parallels of my work to storytelling rituals in remote Filipino hunter-gather societies (December 2017).
Dr. Naci was awarded Trinity College Provost’s Scholarship Grant and will be hiring a new PhD student for a 4-year project, starting from September 2018.
Dr. Naci was awarded the Global Brain Health Institute Project Grant to develop early biomarkers of Alzheimer’s disease in midlife, asymptomatic individuals at high-risk for developing Alzheimer’s.
