Marcel Sayre

Marcel is a Postdoctoral Researcher studying the evolution of neural circuits that underly navigation in arthropods. Over the years, Marcel has developed expertise as a neuroanatomist, using various imaging techniques to understand how brains in diverse animals are organised. During his doctoral studies, he spent time working at the Centre for Microscopy and Microanalysis, (University of Queensland) where he successfully developed a workflow utilising serial block-face electron microscopy to generate connectomic data sets of large brain volumes. This approach allowed Marcel to acquire extensive datasets encompassing multiple species of insects and crustaceans. By comparing homologous navigational brain areas across distantly related species, Marcel’s work sheds light on the fundamental regions of neural circuits that have persisted throughout evolutionary time. These regions play a crucial role in various navigational behaviours, such as long-distance migrations, path integration, and visual homing, which are vital for ecological balance and survival.
