Derick Okwan
Assistant Professor of Pathology
Current Research and Scholarly InterestsBroadly, the Okwan lab’s primary interest is to understand how and why the immune system contributes to nearly all chronic diseases. The immune system of the modern human has evolved from a history of stress to the species: famines, continual bouts of lethal pandemics, as well as major climate/environmental and migratory changes that exposed the immune system to novel threats. At the forefront of these challenges are innate immune cells, particularly neutrophils, the most abundant leukocytes. For the first time in human history – at least in the western world- we live in an era of abundance. The Okwan lab is interested in understanding how this traumatic history creates a functional mismatch for the neutrophil, which we believe underpins their roles in chronic diseases of the modern era: cancer, cardiovascular disease, neurodegeneration, and autoimmune disorders. Rather than wholesale depletion of neutrophils and innate immune cells, we seek to identify novel approaches to leverage these cells to combat various diseases.

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. -

Alan C. Pao
Associate Professor of Medicine (Nephrology) and, by courtesy, of Urology
Current Research and Scholarly InterestsWe are broadly interested in how the kidneys control salt, water, and electrolyte homeostasis in the body. Our disease focus is on kidney stone disease. We use cultured kidney cells, transgenic mice, human plasma/urine samples, and electronic health record data to study the pathogenesis of kidney stone disease. Our therapeutic focus is on the development of small molecule compounds that can be used for kidney stone prevention.

In addition to her clinical responsibilities, she currently is a clinical assistant professor of medical oncology at Stanford School of Medicine. She mentors medical residents and fellows by sharing her insights, knowledge, and expertise.
Dr. Parikh has a strong research background. She has published in multiple academic journals and presented her findings through poster and oral presentations at various medical conferences. -
Victoria Parikh
Associate Professor of Medicine (Cardiovascular Medicine)
BioDr. Parikh is a clinician scientist who cares for patients with and studies inherited (genetic) cardiovascular disease. She is the director of the Stanford Center for Inherited Cardiovascular Disease (SCICD) which is one of the largest of its kind in the country. SCICD integrates clinical and basic science with the expert care of patients with genetic cardiovascular conditions (e.g., cardiomyopathies, arrhythmias and vascular diseases). It provides cutting edge care for thousands of patients and families across the lifespan and integrates medical, surgical and genetics care. Our team includes physicians, nurses, advanced practice providers, genetic counselors, exercise physiologists and scientists.
Dr. Parikh's own clinical practice and laboratory are focused on the genetics of cardiomyopathies and their associated arrhythmogenic substrates. She completed clinical cardiology fellowship at Stanford School of Medicine and her medical residency at the University of California, San Francisco. Funded by multiple research grants from the NIH, her lab seeks to identify novel mechanisms and therapeutic technologies for genetic cardiomyopathy as well as better understand the natural histories of patients affected by these diseases. -

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.
