Biography

Dr. Daniel Peterson is an assistant professor of pathology and medicine at the Johns Hopkins University School of Medicine. Clinically, he works as a diagnostic immunologist. His research focuses on the immunopathology of the gut.

Born an immunologist into a family of farmers, Dr. Peterson grew up working with his father, uncle and brother on a diversified farm of sorghum and soybeans plus pigs and cattle just outside of Lincoln, NE. He studied agriculture at the University of Nebraska-Lincoln where he received a B.S. in animal science. He then left farming to pursue his passion for immunology as an M.D./Ph.D. student at Washington University in St. Louis, working with Emil Unanue during his thesis years. He also completed a residency in pathology and a fellowship at Washington University.

His research team is currently researching the complex systems in play in the host-microbial interactions in the gut in both homeostasis and disease.

Dr. Peterson is board certified in clinical pathology.

    Research Summary

    Dr. Peterson’s research focuses on the basic questions about the factors that determine the impact, level and specificity of the immune response to different microbes. During his postdoctoral training, his research became focused on the immune response gut microbiota, in an era when sequencing the genomes of the gut microbes brought to light a new understanding of this microbial community that occupies the mammalian gut habitat.

    After his fellowship, he moved back to Lincoln and the University of Nebraska-Gut Function Initiative to set up a research group and germ-free mouse facility to examine the host-microbe response in a simplified and defined mouse model. Trained as a clinical pathologist, he has moved to the Johns Hopkins School of Medicine to work in the pathology department as a diagnostic immunologist as well as continue the work on host-microbial interactions in the gut and defining the role that these play in development of the immune system.

    Lab

    The Peterson laboratory uses a "systems immunology" approach to study the complex systems in play in the host-microbial interactions in the gut in both homeostasis and disease. The laboratory uses metagenomic approaches to study the microbes and microbial taxa that are in healthy states compared to disease states in both human subjects as well as mouse models of disease (from Ulcerative Colitic to Small Bowel transplant). Basic cellular immunology of T cells and B cells that are specific to gut microbes with studies that are designed to study the specific impact of gut microbes on the development of specific and non-specific cells in the gut as well as measuring the impact of these immune responses on individual microbes and the microbial community. The systems immunology approach relies on the simplified models that can only be obtained in gnotobiotic and germ-free mice where the microbial composition in the gut can be controlled or removed from the experiments. The Peterson laboratory is in the process of establishing the only gnotobiotic mouse facility at JHU.
