Background

Research in the Bredy laboratory is aimed at elucidating how the genome is connected to the environment through epigenetic modifications, and how this relationship shapes brain and behaviour throughout life. The group is particularly interested in how epigenetic mechanisms, including DNA methylation, histone modifications. the activity of non-coding RNAs, and RNA modification regulate the formation and maintenance of associative fear-related memory.
