Research Interests

Our multi-disciplinary research program focuses on molecular, metabolic, and immunological aspects of cellular and behavioural neuroscience, with a special focus on mechanisms of gene regulation. Current projects explore the potential role of chromatin remodeling genes, DNA methylation and DNA repair mechanisms in social, emotional and cognitive development. Additionally, our lab examines altered metabolism and gene regulatory networks in cancer and neurodegenerative disease.

Our research employs several state-of-the-art molecular, cellular, and behavioural assays to provide a complete picture of how experiences propagate from external to internal variables, and the role chromatin structure and remodelling genes play in neurobehavioural development.

Through cross-appointments with the Departments of Pathology and Psychiatry, and as a member of the Brain Repair Centre (www.brainrepair.ca) and the Atlantic Canada Chapter Chair for the Canadian Developmental Origins of Health and Disease Network (www.dohad.ca), my research group is well positioned to advance (epi)genetic profiling and integrative analysis of gene expression and regulation across a variety of animal and human tissues. We have also formed research partnerships with Canadian biotechnology and pharmaceuticals industry to further biomedical applications.
