Laura A. Pace
Clinical Assistant Professor, Medicine - Gastroenterology & Hepatology
BioI am a physician-scientist specializing in neuroimmunogastroenterology with a focus on the diagnosis and care of people suffering from complex multisystem disorders involving the neuroimmune axis. Neuroimmune axis disorders are conditions at the interface of the nervous and immune systems and often involve autonomic nervous system dysregulation, extracellular matrix|connective tissue dysregulation, endocrine dysregulation, and metabolic dysregulation. These conditions disproportionately and more severely impact females and often have an onset after an immune activating event such as an infection, surgery, concussion, or physical trauma. The complex, multisystem nature of these conditions requires the integration of information from multiple domains to diagnose and identify personalized therapeutic interventions. While at the University of Utah, I was part of the NIH Undiagnosed Diseases Network from 2017-2024, an experience that furthered my resolve to develop a precision medicine program focused on neuroimmune axis disorders. I am an ardent patient advocate and serve on the boards of several patient advocacy groups.
I am board certified in Internal Medicine and Gastroenterology through the American Board of Internal Medicine, and Autonomic Disorders through the United Council for Neurologic Subspecialties. Additionally, I have formalized clinical training in Neurogastroenterology and Medical Genetics, and a PhD in Neuroscience. I am a former NIH Building Interdisciplinary Careers in Women’s Health (BIRCWH) Scholar. To date I have published over 120 peer reviewed scientific articles and have received research funding from the NIH and private foundations.
My research has spanned the study of mammalian cell signaling; the physiology, ecology, and evolution of microbial metabolism; and human-microbe interactions leveraging multiomics. Through several collaborative multidisciplinary research projects her current work is focused on decoding the molecular and cellular mechanisms of neuroimmune axis disorders. Some of these exciting projects include the application of next-generation environmental microbiology techniques to understand the complex human-microbiota interactions at mucosal interfaces; identifying genetic and environmental contributions to neuroimmune axis disorders; and the development and application of novel therapeutics to treat these disabling disorders. -

Robertson Parkman
Adjunct Professor, Pediatrics - Stem Cell Transplantation
BioMy principal research interests have been the assessment of the immunological consequences of hematopoietic stem cell transplantation including both acute and chronic graft versus host disease and immune reconstitution and the use of hematopoietic stem cell transplantation to treat genetic diseases. My laboratory was the first to suggest that chronic graft versus host disease was an autoimmune disease directed at histocompatibility antigens shared by donors and recipients. The observation leaded to the assessment of the role of thymic dysfunction in the pathogenesis of chronic graft versus host disease. As a pediatric immunologist I have investigated the role of hematopoietic stem cell transplantation initially in the treatment of primary immune deficiency diseases and later the treatment of metabolic diseases, which lead to my involvement in the early gene transfer clinical trials.
