Research Overview

Key Research Areas

  • Genome evolution
  • Gene regulation
  • Genomics and Bioinformatics

Research Overview

Our main goal is to understand how changes in the genome sequence control transcriptional change during developmental, regenerative and evolutionary processes. By applying regulatory genomics and computational strategies, we aim to understand how genetic and epigenetic signals are propagated to gene expression, and how this in turn has consequences on higher biological processes. To do this, we produce high-throughput data and use statistical models but also go beyond to dry lab to generate molecular data in different organisms to address fundamental questions that have consequences in both health and disease.

Research Projects

There are 3 key projects underway in the Regulatory Systems Laboratory, led by A/Prof Emily Wong;

1. Tracing regulatory evolution

Most disease loci lie in non-coding regions of the genome and are enriched at enhancers and promoters. Enhancers are rapidly evolving and most enhancers in humans cannot be mapped to the mouse. We use novel concepts, computational and molecular approaches to identify conserved enhancers and understand their mechanism of function and mode of change. This research was recently published in Science.

2. Regeneration genomics

We aim to study the systems biology of heart regeneration to better understand the restorative mechanisms of cells in damaged hearts in vertebrates. Regeneration has been studied in a range of animals but the zebrafish is the most extensively-studied vertebrate model for heart regeneration. We use quantitative strategies to understand how regulatory systems change during the repair process.

3. Regulatory variation during ageing

We are using single cell multi-omics approaches to study how tissues change in ageing animals
