PhD positions in Sensory Biology Institution: La Trobe University, Melbourne, Australia Start: 2026 We are seeking two PhD students to join a research group investigating the evolution and function of sensory systems and coloration, with a particular focus on insects. The projects address how animals perceive their environments, how sensory constraints and ecological conditions shape signal design, and how these interactions influence behaviour and fitness. Students will be based in the School of Agriculture, Biomedicine and Environment at La Trobe University and will be part of a collaborative, international research network. Project 1: Evolution of deep-red vision and infrared sensitivity in jewel beetles This project investigates how jewel beetles detect and use long-wavelength light and heat cues, and why these sensory abilities have evolved. Key questions include how deep-red vision and thermal sensing contribute to habitat selection, mate finding, and host detection. The project combines field and laboratory approaches, including behavioural experiments, electrophysiology, and microscopy, and involves collaboration with international experts in visual and thermal sensory biology. Project 2: Evolutionary functions of animal coloration in predator-prey interactions This flexible project focuses on how animal coloration evolves in response to sensory systems, ecological context, and selection imposed by predators and prey. Possible themes include signal detectability, camouflage, warning coloration, and how environmental conditions alter perception and signal efficacy. Work will primarily involve invertebrates (e.g. insects and spiders) and integrate behavioural ecology, sensory physiology, anatomy, and biomechanics. Environment and training La Trobe University is located in Melbourne, Australia, and offers a vibrant research environment with access to modern facilities and a diverse academic community. Students will receive training in evolutionary theory, experimental design, and quantitative approaches, and will be encouraged to develop independent, hypothesis-driven research programs. Applicants should have a strong interest in evolutionary biology, sensory ecology, or behavioural ecology, and hold a First-Class Honours or Master's degree (or equivalent). Prior research experience and publications are advantageous.
