Robbie is currently a PhD candidate and research assistant. Robbie's PhD project aims to investigate the use of existing technologies and repurpose them for studies into microbial interactions. Interaction studies are cumbersome and mostly limited to pairwise interactions. Robbie's project uses FiSH and acoustically focused flow cytometry to identify gross changes in a microbial population over time, separating the many taxa. This method has high throughput and can go beyond pairwise interactions into three-way or higher interactions up to the limitation of the instruments.
