@GiveWell 5/ Looking for someone with a quantitative advanced degree (epi, env engineering, env health, econ, etc.) and substantial water sector experience. You don't need to know all the new areas! If you're unsure, apply.

1/ My team @GiveWell is hiring a Senior Water Researcher. If you've spent your career thinking about clean water and service delivery and want a job where your research actually decides where tens of millions+ of dollars go — take a look.

@GiveWell 4/ This hire will help us figure out which of those actually clear our cost-effectiveness bar, and think through the thorniest research questions we face. Team is small (3 people right now) and lots of room to shape the agenda.

As our research capacity has grown, so has our ability to fund different kinds of programs—like clubfoot treatment.

We recently learned that about 1/3 as many people used Evidence Action’s chlorine dispensers as we previously estimated in Malawi and Uganda (~5m ppl vs <2m). Here, we dig into what happened, how we learned about it, and next steps for dispensers and chlorination more broadly.

Sometimes a program can do a lot of good but not have the impact per dollar we expected.
