Why would anyone want to make a bacterium glow in the dark?

Faraz Alam (PhD in Infectious Diseases from Imperial College London) wants to tell you why he spent the last four years of his life making bacteria glow in the dark, who gave him the money to do that and why mad science like this is important.

Also you may hear stories about how he accidentally made a vagina glow in the dark, how blogging about flatulence changed the way he did his research and why sometimes the best thing to happen to you in science is to get things wrong.
