Apple obtained her Bachelor of Engineering with Honours in Chemical and Biomolecular Engineering from The University of Melbourne. She continued to pursue a PhD with the Department of Chemical and Biomolecular Engineering and School of Chemistry, in partnership with Dairy Innovation Australia, to understand the impact of ultrasound on dairy solutions and the application of ultrasound on the productivity of dairy membrane filtration systems. During her PhD, Apple had the opportunity to work as a teaching assistant for the undergraduate Chemical Engineering subjects. Her responsibilities included delivering tutorials and supervising undergraduate students in their final year research projects.
