Microbiologist Joe Latimer is a postdoctoral research associate at the University of Manchester. He built the Microbial Zoo for our Decontamination Unit at Glastonbury, and introduced muddy guests to the flora and fauna of the human body all weekend at Britain’s biggest, dirtiest festival. He came back for more, building a second Microbial Zoo for Bestival (this time, using bacteria drawn from his own body), and delivering a lecture on why we need our bacteria just as much as they need us. Plus, we helped him overcome his fear of snakes!
