James Versalovic, MD, PhD

Dr. Versalovic serves as Pathologist-In-Chief at Texas Children’s Hospital and Director of Texas Children’s Microbiome Center. He is the Milton J. Finegold Professor and Vice Chair of Pathology & Immunology at Baylor College of Medicine.  He also is Professor of Molecular and Human Genetics, Molecular Virology & Microbiology, and Pediatrics, and Co-Director of the Medical Scientist (MD/PhD) Training Program at Baylor College of Medicine.

Dr. James Versalovic received his M.D. with Honors at Baylor College of Medicine (BCM) in 1995 and his Ph.D. in Cellular and Molecular Biology at BCM in 1994. He pursued clinical pathology/medical microbiology residency training at the Massachusetts General Hospital and Harvard Medical School. He also completed a postdoctoral research fellowship in the Division of Comparative Medicine at the Massachusetts Institute of Technology (MIT). Dr. Versalovic joined the medical staff as a clinical pathologist at the Massachusetts General Hospital and served as Assistant Professor of Pathology at Harvard Medical School. He is board-certified in clinical pathology, molecular genetic pathology, and molecular diagnostics.

Dr. Versalovic directs the delivery of diagnostic services and laboratory medicine at Texas Children’s by serving as Director of Laboratories, for the medical center campus. Dr. Versalovic’s main clinical interests are medical microbiology, molecular diagnostics of infectious diseases, microbiome science applies to pediatric gastroenterology, genomic and metagenomic medicine, and molecular pathology. Dr. Versalovic has created the first microbiome center based in a children’s hospital and the first therapeutic microbiology fellowship program in the country. He has helped create the new field of metagenomic medicine by exploring ways that metagenomics and microbial manipulation can be used to diagnose and treat human diseases. He served as Editor-in-Chief of the Manual of Clinical Microbiology, the “bible” of laboratory-based diagnosis of human infections.

As Principal Investigator since 1999, Dr. Versalovic’s primary research areas include gastrointestinal microbiology, the human gastrointestinal microbiome and mechanisms of signaling between the microbiome and human cells. With a focus on the gastrointestinal microbiome, beneficial microbes and chronic disease, Dr. Versalovic’s research team has studied mouse models and human subjects/patients to understand basic concepts of microbiome science, human microbiology, and how the microbiome impacts human development and children’s health. Dr. Versalovic is advancing metagenomic medicine and its applications in chronic gastrointestinal disorders such as pediatric irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). His research program has been supported by the U.S. National Institutes of Health, Department of Defense, and Crohn’s and Colitis Foundation of America. Dr. Versalovic has authored more than 135 primary manuscripts, more than 30 book chapters, and 2 patents.
