Science Editor

Flora obtained a PhD in Biological Sciences from Nanyang Technological University in Singapore. During her doctoral studies, she examined how a human-colonising microbe could evolve in response to changes within a mammalian host, and how this process could influence microbial virulence. After a brief stint as a postdoctoral fellow at the Institute of Molecular and Cell Biology, she joined Health Feedback in 2018 as science editor.
