Rebecca studied Psychology at the University of York before working in a variety of roles - in both the UK and internationally - where she assisted individuals with neurodegenerative and developmental conditions. She then completed her science teacher training with the National STEM centre, Royal Society of Chemistry and the Association for Science Education. Rebecca teaches biology and chemistry at Key Stage 4 and general science at Key Stage 3, and has also ran neuroscience and eco clubs at her school.
