Julie did her PhD in Structural Biology of the regulation of cell cycle complexes in the LMB, University of Oxford with Prof Jane Endicott and Prof Martin Noble. She spent one year in Eva Nogales's laboratory at UC Berkeley to further study mitotic protein complexes by electron microscopy. She joined the Cheeseman lab, at the Whitehead Institute and MIT, Boston, in 2008 to pursue cell biology and biochemical studies on mitosis.
Julie received a CRUK research career development and moved in April 2012 to the Wellcome Trust Centre for Cell Biology, Edinburgh to start the lab and study the molecular basis for motors in cell division. Since August 2018, she is Wellcome Senior Fellow.
