Olivia O'Leary


Olivia O'Leary is a Senior Lecturer and Principal Investigator in the Department of Anatomy and Neuroscience, and a Funded Investigator at APC microbiome Ireland, University College Cork. Dr O’Leary leads a research programme investigating the neurobiology of stress-related psychiatric disorders such as depression, thus aiming to identify novel targets for therapeutic development. Part of her research programme investigates gut microbial regulation of the generation of new neurons in the hippocampus area of the brain and the implications that this may have for cognitive and stress-related brain disorders. Dr O’Leary also investigates interactions between the gut microbiota and female brain health during hormonal transition periods of life that may potentially contribute to increased susceptibility of females to stress-related psychiatric disorders.
