Professor Parish’s research is currently focused on the molecular biology of transcriptional control and persistence of HPV, hepatitis B virus (HBV) and other small DNA viruses. Her recent research has identified an essential role for the host transcription factors CTCF and YY1 in the control of differentiation-dependent virus gene expression and her research has unravelling the mechanism of HPV transcription control through epigenetic regulation. She continues to address long-standing questions about HPV gene expression control and replication using novel and state-of-the-art technologies.
