David is a Consultant Paediatrician, Metabolic Physician, Clinical Geneticist and clinician researcher. His area of expertise is the diagnosis and management of children with rare diseases. David is involved in multiple ongoing research projects aimed at novel disease discovery, improved diagnostic testing and treatments for children with inherited genetic disorders. He is director of a national clinic for Ataxia Telangiectasia brashat.org.au and has recently been awarded a $2.5 million NHMRC research grant for a phase 2/3 trial for treatment of this disorder.
Evolutionary and ecological genomics of marine invertebrate animals.
Animals evolve because their genomes need to respond to the constantly changing environment presented by both their external habitat and their internal microbial symbionts. Over evolutionary time, these different factors interact during development, when the animal body plan is being established, to generate the extraordinary animal diversity that graces our planet. In ecological time, early life history stages must detect and respond to the precise nature of their environment to generate a locally-adapted functional phenotype. Using coral reef invertebrates from phyla that span the animal kingdom, we study these gene-environment interactions using genomic, molecular and cellular approaches combined with behavioural ecology in natural populations. We work mostly with embryonic and larval life history stages of indirect developers, as these are crucial to the survival, connectivity, and evolution of marine populations. When not immersed in the molecular or computer lab, we are lucky enough to be immersed in the ocean, often in beautiful places!

Dr. Palpant’s research team has expertise in human stem cell biology, computational genomics, and cardiac physiology, which enables them to translate outcomes from cell biology and genomics to disease modelling, drug discovery, and preclinical modelling.
My research interests are at the intersection of plant developmental genetics, functional genomics, and molecular and systems biology, following my doctoral and postdoctoral training in the USA. The research effort in my group is focused on harnessing transformative genomics technology to understand the genetics of plant development, and to discover regulatory mechanisms coordinating plant growth and development. We utilize a variety of plant species in our research, from the model plant organism Arabidopsis to grain and horticultural crops like wheat, mango, avocado and macadamia. We employ a range of techniques based on high throughout DNA sequencing to explore gene expression, chromatin accessibility and modifications from single cell to whole plant levels, bioinformatics and computational biology tools to infer genetic components of gene regulatory networks, as well as gene editing technology to evaluate phenotipic consequences of perturbations in gene regulatory networks.
