A method for discovering gene function in microbes developed by Adam Arkin, Adam Deutschbauer, Vivek Mutalik, and Pavel Novichkov of the Environmental Genomics and Systems Biology division has been shortlisted for R&D Magazine’s 2017 R&D 100 Award. The technology, called Dual Barcoded Shotgun Expression Library Sequencing (Dub-seq), combines the shotgun expression library method and next generation sequencing method developed through the ENIGMA program. Now in its 55^th year, the prestigious R&D 100 Awards program recognizes the most innovative inventions of the prior year. The winners will be announced and honored at a black-tie ceremony to be held this fall in conjunction with the annual R&D 100 Conference.
