During training, she took time out to undertake a PhD (University of London, 2011). Her research investigated the role of selenium, an essential micronutrient, in sensitising cancer cells to chemotherapy. She was able to show that supra-nutritional doses of selenium could enhance the action of chemotherapy in the laboratory.
