Before its acquisition in 1998 by Cognetix - itself an SBR involved firm that took over the work onthe Viatech awards, Viatech had been involved in high-throughput functional screening with advanced systems for cell-based assays. Viatech's two senior scientists joined Cognetix in conjunction with the acquisition. Ann Cornell-Bell, Ph.D., formerly of Yale University School of Medicine and a pioneer in the use of confocal microscopy for cell imaging, assumed the post of Director of Drug Discovery. Leslie Riblet, Ph.D., who played key roles in central nervous system drug discovery and development at Bristol-Myers Squibb, joined the Company as Director of Drug Development.
