Research Interests

Research summary
As a member of the Gavin Kelsey laboratory, my primary research interest is to understand how DNA methylation marks are established in the female germ line and what is the impact of such marks on early-embryo development. I am particularly interested in the role of transcription in DNA methylation establishment at the imprinted gene Zac1 gDMR, and the physiological consequences of Zac1 loss-of-methylation and bi-allelic expression.
