Proud of my group of rising clinicians and scientists.
I am Associate Professor of Psychology and lead the 'Consciousness and Cognition' Group at the School of Psychology, Trinity College Institute of Neuroscience and Global Brain Health Institute, Trinity College Dublin.
A major focus of my group is the investigation of the functional brain organisation that supports human cognition and consciousness, and how this organisation 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 of my work 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 earliest cognitive/functional changes, and their underlying pathophysiologic mechanisms. This can lead to earlier diagnoses, potential targets for treatment, and better understanding of the disease itself. We carry out this work in collaboration with colleagues from Edinburgh, Cambridge and Oxford Universities (UK), within the PREVENT consortium.
Trinity College Dublin launches a new initiative in NeuroHumanities, aiming to stimulate public engagement and generate exciting research at the inter-disciplinary boundary between humanities and brain sciences.
