Jennifer Doudna was a pioneer of CRISPR, which is a gene-editing technology that is being increasingly studied and used across the world. Jennifer relates the genesis of CRISPR to us and explains the pros and cons of giving birth to such a potentially world changing process. On the positive side, she tells us how scientists are already combining her technology with stem cell research to potentially rid the world of sickle cell anemia. On the negative side, she describes a vivid nightmare she had early on in the process wherein she meets Hitler with a pig nose—a David Lynch-ian vision that represents the negative possibilities of what could happen if CRISPR falls into the wrong hands. While the Pig Hitler scenario is a lot less likely to actually happen, Jennifer understands the duality of her role in CRISPR's creation.Jennifer Doudna's most recent book is A Crack in Creation Gene Editing and the Unthinkable Power to Control Evolution.
