Tapoka Mkandawire is a PhD student in parasitology & genomics at the Wellcome Sanger Institute. She studies neglected tropical diseases, which affect hundreds of millions of people worldwide but aren't that well known in the UK.

Tapoka talks about what’s causing the reducing rates of these diseases, and what role the gut microbiome plays in parasite life-cycle. From researchers who self-infect themselves with whipworms, to citizen science projects, and the crucial role the gut microbiome plays in everyone’s life.
