Ivan Vujkovic-Cvijin, PhD, is an assistant professor in the Department of Biomedical Science, Karsh Division of Gastroenterology, and the F. Widjaja Inflammatory Bowel Disease Institute of Cedars-Sinai. Dr. Vujkovic-Cvijin studies how microbes that inhabit the human gut contribute to inflammatory diseases including inflammatory bowel disease. He pioneered the study of gut bacteria in HIV disease progression and has helped identify confounding variables and best practices for human microbiome association studies. In pursuit of understanding causal roles of gut bacteria in inflammatory disease, he has developed novel omics tools to quantify immune responses to the microbiota. Dr. Vujkovic-Cvijin's research group uses microbiology, immunology, ecology, and data science to carry out translational work with the goal of improving human health and alleviating disease.
