She, along with Emmanuelle Charpentier, developed CRISPR to study the effects of genes in human development. Doudna wrote that the “real excitement–and power–in genetics lies in manipulating the genome to alter DNA so we can prevent disease and improve human help” (TIME). CRISPR will answer questions about the earliest stages of reproduction. Jennifer Doudna’s work is single-handedly redefining modern science and represents the most profound chance to better the human condition.
