Profile: building a world-class lab from scratch.

In 1996, Projet RETRO-CI, a U.S.-Ivoirian collaboration funded by the U.S. Centers for Disease Control and Prevention, hired virologist John Nkengasong to build a virology lab from scratch. Now Nkengasong runs one of the best equipped HIV labs in sub-Saharan Africa and has published dozens of papers helping to clarify properties of specific strains of the virus.
