Professor Ryan Lister
Professor Ryan Lister PhD completed his Bachelor's degree in Biochemistry and Genetics at The University of Western Australia (UWA) in 2000, and undertook his PhD studies in plant mitochondrial biogenesis at UWA from 2001-2005. After completing his PhD, Ryan was awarded a Human Frontiers Science Program Postdoctoral Fellowship in 2006 to undertake his postdoctoral studies in Joseph Ecker’s laboratory at The Salk Institute for Biological Studies in California, where his research focused on studying the epigenome, the molecular code superimposed upon the genome that plays important roles in regulating the information contained in the underlying DNA sequence. He developed new high-throughput DNA sequencing methodologies to profile the transcriptome and epigenome, including the first RNA-sequencing approach and whole genome bisulfite sequencing. This allowed, for the first time, the precise mapping of sites of DNA methylation throughout an entire genome. Ryan returned to Perth in 2012 to establish his own research group, and is currently a Sylvia and Charles Viertel Senior Medical Research Fellow and head of the Epigenetics and Genomics laboratory at the Harry Perkins Institute of Medical Research and UWA. His research has yielded new insights into the composition and function of the epigenome in a variety of systems, including the first integrated maps of the epigenome and transcriptome in a eukaryote, generation of the first human DNA methylomes, identification of epigenomic memory in human induced pluripotent stem cells, and discovery of widespread epigenome reconfiguration during brain development.
Almost every cell in the body contains essentially the same genome sequence, however differential usage of the genetic information enables cells with vastly different features and functions to be formed. The epigenome is a molecular code superimposed upon the genome that can control how genes are turned on and off, without altering the underlying DNA sequence. By modulating accessibility and usage of the information encoded in the genome, epigenetic modifications can affect gene activation and repression to execute distinct transcriptional programs and impart a stable state of transcriptional activity. Developing a comprehensive understanding of how the cell utilizes the epigenome is essential in order to both understand the critical roles it plays in cell differentiation and development, and to develop effective strategies to remedy its disruption in disease states.
DNA methylation is a central epigenetic modification that imparts an additional layer of information upon the DNA code, playing critical roles in processes including genome defense, gene regulation, development, and disease. However, fundamental questions remain regarding the processes that govern the establishment of epigenome patterns and how the cell interprets them to affect changes in chromatin structure and gene expression. Revolutionary advances in DNA sequencing technology in the past few years now allow identification of the sites of DNA methylation at single base resolution throughout entire genomes. Integration of these maps with deep molecular profiling of genome accessibility, histone modifications, and transcriptional activity are revealing unanticipated composition and dynamics in the epigenomes of complex multicellular organisms.
Ryan’s research uses advanced genomic, molecular, genetic and computational techniques to study the epigenome, including using next-generation sequencing technologies to generate whole-genome high-resolution maps of the epigenome and associated molecular processes (e.g. whole genome bisulfite sequencing, RNA-seq, ChIP-seq, ATAC-seq). His research aims to elucidate the mechanistic underpinnings of how the epigenome is established and dynamically modified, how it affects the cellular readout of the underlying genetic information, and to develop molecular tools for editing the epigenome.
