Cancer research scientist and childhood cancer survivor. I am a postdoctoral research scientist focusing on childhood cancers and new, targeted cancer therapies. As a survivor of childhood leukemia myself, I am a determined advocate for research into better, less-toxic cancer treatments and how to reduce the long-term side effects of current drugs. I am an award-winning science communicator and have written for The Times, The Guardian and various cancer-focused outlets. I am also a 2017 TED Fellow, having done my TED talk this year on cancer survivorship and I regularly do public talks on topics ranging from ‘Why haven’t we cured cancer yet?’ to ‘Cannabis and cancer; hype or hope?’. I am passionate about using social media to communicate science and frequently share pictures and stories from my own laboratory work in real-time on my Twitter account @vickyyyf, alongside commentary about important research breakthroughs.
