Abdoulaye Diabate faced a life-threatening bout of malaria when he was just five years old. Diabate narrowly survived the mosquito-borne disease, but cousins ages three and four were not as fortunate.

Diabate, who now heads medical entomology and parasitology at Burkina Faso’s Research Institute in Health Sciences, is developing an innovative technique that could potentially wipe out malaria-transmitting mosquito species by altering their genes.
