Chelsie Rohrscheib moved to Australia from the United States to complete her graduate studies in molecular biology. In 2015 she completed a PhD in neurobiology with a focus on how host-symbiont interactions, especially bacteria that exist in the gut and the brain, affect the nervous system and host behaviour. She is currently a postdoctoral research fellow in the van Swinderen lab at the Queensland Brain Institute at the University of Queensland. Chelsie’s current research focuses on the regulation of sleep behaviour and the molecular mechanism underpinning sleep, in the fruit fly, Drosophila melanogaster. She has a particular interest in the interaction between sleep dysfunction and neurological disorders such as depression, autism, and schizophrenia.
