Witold Wiecek will be discussing how to actually know how effective different global health interventions are, with a special focus on the case of water & water distribution.

Witold also happens to be one of the foremost Bayesian statisticians in the world (!), and was one of the most influential voices for spending more on advance market commitments for Covid vaccines (he’s also been a good friend for some years now). You can see some background about him on his site: https://wwiecek.github.io/about/. He’ll give an informal talk, and then we’ll hang out in the pub after. Hope to see you there!
