Dr. Antonopoulos joined the IGSB and Biosciences Division at Argonne National Laboratory in June 2008 and holds a joint appointment in the Department of Medicine, Section of Gastroenterology, at the University of Chicago. Dr. Antonopoulos is a microbiologist interested in studying the formation and development of microbial communities. His interest in understanding mammalian gastrointestinal function has been complemented by ongoing research in environmental systems (subsurface and topsoil systems).  Although the scales are vastly different between the two, many of the approaches used in both GI and field research are steeped in classical ecological theory and serve to circumnavigate the complex nature of the microbial communities underlying system function. His group is actively involved in applying second-generation DNA sequencing technologies to describing both the structure and function of microbial communities in these systems and has taken advantage of the computational resources available at Argonne National Laboratory (ANL, http://www.igsb.org/services/hgac/) to handle the scale of data afforded by these technologies. His joint appointment between the University of Chicago (Dept of Medicine) and ANL, via the Institute for Genomics and Systems Biology, enables interactions between the clinical and next generation laboratory approaches (including shotgun metagenomics) to understanding the microbial world.
