about

I'm a data journalist and infectious disease epidemiologist based in London, England. I'm interested data's capacity to inform, whether to influence large-scale policy or to aid individuals in learning about and making decisions in the world around them. I love to collaborate, learn from others, and help where I can. In my free time, I'm likely exploring the city or finding my new favourite noodle soup shop.
