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!
I am a developmental neuroscientist and bioinformatician interested in the molecular evolution of the mammalian brain. I completed a PhD on the molecular development of vasculature in the primate retina at the Australian National University, followed by a postdoctoral position at the Institut de la Vision in France that was supported by a NHMRC CJ Martin fellowship, where I investigated the role of guidance factors in the formation of commissural neurons within the mammalian hindbrain. My current research focuses on the development and evolution of the mammalian forebrain, in particular understanding the regulatory mechanisms and molecular evolutionary processes that control specification of cortical neuron subtypes.
I am a biologist interested in the general question of how changes in developmental processes can lead to evolutionary variation and origin of complex traits (such as neural circuits). I study development and evolution of the brain of mammals. My doctoral thesis studied brain regions involved in olfactory and pheromonal communication in mammals. I discovered several events of parallel co-variation of sensory pathways in distantly related species sharing similar ecological niches, as cases of ontogenetic and phylogenetic plasticity. Currently, I study development and evolution of neocortical circuits by following two main lines of research: one aims to determine how early neuronal activity emerges during development and help shape brain connections, and the other one aims to understand what developmental processes led to evolutionary innovations in the mammalian brain. My research combines molecular development (electroporation, CRISPR), transcriptomics, sensory manipulations, neuroanatomy mapping (MRI, stereotaxic tracer injections, confocal and image analysis), optogenetics, and in vivo calcium imaging (multiphoton and widefield) in rodent pups and marsupial joeys.
