My research focuses on the evolution senses and brains in reptiles. I like to take an integrative approach by using morpological, molecular and behavioural data to understand the evolution of complex sensory traits.
My current projects include an ARC Discovery Project investigating brain evolution in Australian squamates (snakes and lizards). This project aims uses diffusible iodine contrast-enhanced CT scanning to capture changes in brain shape and size during transitions to new ecologies/biomes. This research dovetails with development projects on how incubation temperature is impacting brain development in thermo-sensitive species like bearded dragons.
My current ARC DECRA project investigates the mechanisms underlying sensory adaptations in snakes. This research will harness innovative phenotypic imaging and genomic sequencing, to study the coordinated changes among sensory systems in a range of ecologically diverse snakes. Expected outcomes include a large database of 3D digital anatomical models from Australian and international museum collections, and new knowledge on the genetic processes influencing sensory receptor evolution in vertebrates.
These projects have benefits for conservation by using neural adaptability as a framework for estimating potential extinction risk for vulnerable species.
I am also passionate about conservation in sea snakes, helping to create an environmental DNA (eDNA) assay for detecting endangered sea snake species in Western Australian Marine Parks.
