Malaria kills about 400,000 people per year with millions more falling ill - 70% of these people are children under 5 years old. Rob Mather and his team at the Against Malaria Foundation are working to solve this massive problem.

Rob Mather is the founder and CEO of The Against Malaria Foundation. AMF has now raised more than $230 million, funding more than 100 million anti-mosquito bed nets protecting millions of people.

AMF uses technology, rigorous processes and clear accountability to ensure aid is delivered effectively. For seven of the past eight years, AMF has been a top-ranked charity of the independent charity evaluators GiveWell and The Life You Can Save.
