Research Interests

The role of DNA methylation and chromatin remodeling in mammalian development, with a life course perspective on neural adaptation and responses to stress and possible therapeutic and dietary intervention. Dr. Weaver’s research employs a wide range of techniques—e.g., bisulfite sequencing, ChIP analysis, RT-qPCR, ELISA, primary culture systems, epifluorescence microscopy and animal behaviour tracking—for the molecular, cellular and physiological evaluation of defensive systems (e.g., stress, immune and DNA damage pathways) underlying common human diseases, including autism spectrum disorder, metabolic syndrome, cancer and neurodegeneration. 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), his research group is well positioned for (epi)genetic profiling and integrative analysis of chromatin architecture across animal and human tissues.
