Since its founding in 1982, Quintiles has become a leading clinical research organization, from first-in-human studies to post-launch monitoring. In 2013, Quintiles acquired Expression Analysis (EA) to expand its genomic testing analysis services throughout the entire process of drug discovery and development. Dr. Patrick Hurban, a trained molecular biologist and geneticist and EA’s Global Head of Genomic R&D, tells Nature how the marriage between EA and Quintiles benefits researchers.
