It’s been 20 years since Andrew Hopkins, founder and CEO of artificial intelligence drug research firm Exscientia plc, co-authored the seminal paper “The Druggable Genome,” which laid the foundations for the company and gave insights about how to make research more efficient and less costly. Now Hopkins’ colleagues at Exscientia have taken stock of progress in a new paper, “The druggable genome: Twenty years later,” that summarizes advances in the field and evolution in thinking over the past two decades.
