Ros completed her PhD in 2020. Her studies covered the structural and biochemical factors affecting apple response to long-term low oxygen stress. She is particularly interested in dynamic controlled atmosphere (DCA) storage techniques. She is now working on monitoring the physiological status of potato tubers in situ during storage, working closely with Storage Control Systems Inc. on a new development of the SafePod system, the P-Pod.  Prior to her PhD studies, Ros had a career as a patent and academic literature information scientist, specialising in agrochemicals.
