TZU HAN LO
Postdoctoral Scholar, Gastroenterology
BioTzu-Han Lo, a researcher at the Institute of Biomedical Sciences at Academia Sinica, has made contributions to the field of macrophage biology. His work has particularly focused on inflammation, especially in the context of fibrotic response. One of his works includes a study on the regulation of macrophage polarization in ureteral obstruction. This research has illuminated the role of inflammatory cell infiltration and activation during the early stages of kidney injury, a common pathological feature of chronic kidney disease.
In addition to his work on macrophage biology, Tzu-Han Lo has also delved into research related to galectins, a family of β-galactoside–binding proteins. His work in this area has centered on the role of galectins in recognizing microbial glycans, particularly lipopolysaccharides (LPSs). He has explored their impact on host defense mechanisms, including autophagy and both canonical and non-canonical inflammasome signaling pathways.
His research has offered insights into the complex interactions between host immunity and microbial components. This has contributed to our understanding of inflammatory responses and their implications for human health. -

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. -
Jennifer Yi-Jiun Pan
Clinical Assistant Professor (Affiliated), Medicine - Med/Gastroenterology and Hepatology
Staff, Medicine - Med/Gastroenterology and HepatologyBioMy research interests thus far have focused on immunology, GI cancers, and improving quality of care for patients. I am passionate about understanding the different genetic and lifestyle factors that are involved in GI cancers and other colonic pathology, as well as improving systems of care to better manage the health and improve the outcomes of patients with these diseases. Towards that end, I have been involved in research in Lynch syndrome in order to bridge the gap between our current understanding of cancer risk in this high-risk population and the creation and implementation of guidelines worldwide. I also had the opportunity to work with collaborators in the International Mismatch Repair Consortium at the Department of Colorectal Medicine and Genetics with the Royal Melbourne Hospital in Australia where I saw firsthand the global efforts in the fight against colorectal cancer. In my current role as a staff gastroenterologist at the VA Palo Alto, I oversee the colorectal cancer prevention program. My goal is to continue to be part of and contribute to collaborative clinical and research efforts in order to provide the best care for our patients.

Edward A. Pham
Instructor, Medicine - Gastroenterology & Hepatology
BioMy interest in medicine and research was triggered by my mother’s battle with chronic hepatitis C, which made me realize the transformational power of biomedical research in treating patients. Therefore, my career goal is to become a physician scientist in the field of gastroenterology and hepatology dedicated to translating discoveries in the laboratory into novel medical treatment modalities. My research focus is alterations in phosphoinositides signaling and its pathogenesis in cancers of the hepatobiliary and luminal GI tract with the goal to identify novel targets for therapeutic intervention.
