Feng Zhang traces his path from Jurassic Park to RNA-guided gene editing
Start here
CRISPR pioneer Feng Zhang recounts how he moved from disliking biology in high school to becoming a central figure in gene editing, drawn in by Jurassic Park's vision of DNA as life's blueprint. He contrasts earlier editing tools such as zinc finger nucleases and TALENs, which demanded months of protein engineering, with CRISPR-Cas9, which uses RNA base pairing to guide editing of multiple genes within weeks. Zhang first noticed the system at a 2011 talk at the Broad Institute. Using CCR5 as an example, he stresses that editing always involves trade-offs, such as HIV resistance paired with greater susceptibility to West Nile virus, and calls for cautious progress in the field.

CRISPR pioneer Feng Zhang says he disliked biology in high school until Jurassic Park's idea of DNA as life's blueprint drew him in. He describes how early tools such as zinc finger nucleases and TALENs required protein engineering over months, while CRISPR-Cas9, which he noticed at a 2011 talk at the Broad Institute, uses RNA base pairing to guide editing of multiple genes within weeks. Using CCR5 as an example, he stresses that editing involves trade-offs, such as HIV resistance but greater West Nile virus susceptibility, and calls for cautious progress.
