His research focuses on characterizing the microbial communities that are harbored in the human body and in the development of bioinformatic tools for the analysis of high-throughput sequencing data. He received his Ph.D. in 2007 at the Japan Advanced Institute of Science and Technology, and did his postdoctoral work with Drs. Takashi Gojobori (National Institute of Genetics) and Rob Knight (University of Colorado). His lab at Mount Sinai is currently working on building more accurate models of the microbiome in IBD and food allergies, as well as developing tools to analyze multi-omics data for these diseases.
