Subsequently, he returned to the UK in 2005 to work for Plymouth Marine Laboratory as a senior scientist until his move to Argonne National Laboratory and the University of Chicago in 2010. Professor Gilbert was the Director of the Microbiome Center and a Professor of Surgery at the University of Chicago. Currently, Dr. Gilbert is a Professor in the Department of Pediatrics and the Scripps Institution of Oceanography at University of California, San Diego. He is also Group Leader for Microbial Ecology at Argonne National Laboratory, Research Associate at the Field Museum of Natural History, Scientific Fellow at the Marine Biological Laboratory, and the Yeoh Ghim Seng Visiting Professorship in Surgery at the National University of Singapore. Dr. Gilbert uses molecular analysis to test fundamental hypotheses in microbial ecology. He has authored more than 250 peer reviewed publications and book chapters on metagenomics and approaches to ecosystem ecology. He is the founding Editor in Chief of mSystems journal. In 2014, he was recognized on Crain’s Business Chicago’s 40 Under 40 List, and in 2015, he was listed as one of the 50 most influential scientists by Business Insider, and in the Brilliant Ten by Popular Scientist.
