David Berry received his PhD in Environmental Engineering at the University of Michigan, where he investigated the transcriptional response of bacteria to drinking water treatment. In 2009, he joined the Department of Microbial Ecology at the University of Vienna in Austria and began studying the intestinal microbiota and its role in inflammation. He established a research group in 2012 focused on basic and translational aspects of microbiome science, and is currently a Professor at the Department of Microbiology and Ecosystem Science at the University of Vienna as well as director of the newly-founded Joint Microbiome Analysis Facility of the Medical University of Vienna and University of Vienna. His research focuses on the function of the gut microbiota in health and disease and employs an ecological and evolutionary perspective as well as an organismal view by studying the physiology of key gut microbiota members. In particular, his group uses novel modeling approaches to study microbial communities and develops new molecular and isotope-labeling methods and single-cell imaging technologies for studying uncultivated microorganisms in their natural environment.
