    Professor of Medicine, Emerita

    Current Research and Scholarly InterestsThe lab is studying the mechanisms controlling B cell responsiveness and the balance between tolerance and autoimmunity. B cells deficient in CD72 are hyperresponsive to stimulation through the B cell receptor. We are examining the alterations in B cell signaling in these B cells and the mechanisms by which CD72 deficiency partially abrogates anergic tolerance. We hope to learn how deficiency in CD72 leads to spontaneous autoimmunity and increased susceptibility to induced autoimmune disease.

  • Shyon Parsa

    Shyon Parsa

    Affiliate, Department Funds
    Resident in Medicine

    BioShyon earned his B.S. in Biomedical Engineering from the Cockrell School of Engineering at the University of Texas - Austin, graduating with Honors. He completed coursework in Thermodynamics and Transport Phenomena in Living Systems at the Department of Applied Mathematics and Theoretical Physics at Cambridge University under Clare Hall fellow Dr. Kenneth Diller. After graduation, Shyon enrolled in medical school at UT Southwestern, and graduated with an M.D with Distinction in Research and as a member of the Alpha Omega Alpha (AOA) honor society.

    He started his internal medicine residency at Stanford University Hospital in 2023. In 2024, he was awarded a Stanford Cardiovascular Institute Seed Grant for his project "An Artificial Intelligence Approach Utilizing Radiomic-Derived Calcium Features on Calcium Scoring CT (CAC-CT) in Cardiovascular Risk Stratification" (Co-PI). In 2025, he was selected for a Young Investigator Award from the National Lipid Association and named as an American Heart Association Early Career Investigator Award finalist. His works have been highlighted in the New England Journal of Medicine AI, Journal of the Academic College of Cardiology, and Journal of the American Heart Association.

    His interests include the development of AI-enabled ECG models, the implementation and evaluation of AI tools in clinical workflows, and policy surrounding the responsible use of AI in health systems. He is pursuing a career in cardiology with a focus on electrophysiology, medical device development, and policy.

  • Julie Parsonnet

    George DeForest Barnett Professor of Medicine, Emerita

    Current Research and Scholarly InterestsI am an infectious diseases epidemiologist who has done large field studies in both the US and developing countries. We research the long-term consequences of chronic interactions between the human host and the microbial world. My lab has done fundamental work establishing the role of H. pylori in causing disease and understanding its epidemiology. Currently, our research dissects how and when children first encounter microbes and the long term effects of these exposures on health.

    Clinical Professor (By courtesy), Pediatrics

    Current Research and Scholarly InterestsMy research interests involve the epidemiology, treatment and diagnosis of pediatric and young adult brain tumors. I am also interested in long-term neurologic effects and designing clinical trials to treat brain and spinal cord tumors.

  • Gopanandan Parthasarathy

    Gopanandan Parthasarathy

    Clinical Assistant Professor, Medicine - Gastroenterology & Hepatology

    BioDr Nandan Parthasarathy is a hepatologist and physician-scientist in the Department of Gastroenterology and Hepatology at Stanford University.
    After obtaining his medical degree in JIPMER, India, he completed a 2 year clinical research fellowship at Mayo Clinic, following which he completed his residency training at Cleveland Clinic, and GI and transplant hepatology fellowships at Mayo Clinic. During his fellowship, his research work was focused on exploring the immune mechanisms of liver injury in metabolic dysfunction associated steatohepatitis.
    Clinically, he is focused on taking care of patients with MASH, cirrhosis and liver cancer.
    His career goal is to study the gut-immune system-liver injury axis in order to bring novel therapeutics from the bench to bedside in patients with liver disease.

  • Josef Parvizi, MD, PhD

    Josef Parvizi, MD, PhD

    Professor of Neurology and Neurological Sciences (Adult Neurology) and, by courtesy, of Neurosurgery

    BioDr. Parvizi completed his medical internship at Mayo Clinic, neurology training at Harvard, and subspecialty training in clinical neurophysiology and epilepsy at UCLA before joining the Department of Neurology and Neurological Sciences at Stanford in 2007. Dr. Parvizi directs the Stanford Program for Medication Resistant Epilepsies and specializes in surgical treatments of intractable focal epilepsies. Dr. Parvizi is the principal investigator in the Laboratory of Behavioral and Cognitive Neuroscience, where he leads a team of investigators to study the human brain. http://med.stanford.edu/parvizi-lab.html.

  • Anca M. Pasca, MD

    Anca M. Pasca, MD

    Assistant Professor of Pediatrics

    Current Research and Scholarly InterestsI am a physician-scientist, neonatologist, and stem cell biologist whose research focuses on understanding mechanisms of human brain development, neuroinflammation, and neurological injury using patient-derived stem cell models.
    I was among the early pioneers of three-dimensional human cortical organoid technologies and contributed to development of foundational protocols for generating region-specific human brain organoids from pluripotent stem cells. My work helped establish the feasibility of modeling human brain development and disease using stem cell-derived tissues and has contributed to the widespread adoption of organoid technologies across neuroscience, regenerative medicine, and translational research.
    A major focus of my laboratory is the development of increasingly sophisticated multicellular organoid and assembloid systems that incorporate diverse neuronal and glial populations to model complex human brain circuitry and disease processes. We integrate stem cell biology, organoid engineering, CRISPR-based genome editing, single-cell transcriptomics, epigenomics, high-content imaging, and computational approaches to identify disease mechanisms and therapeutic targets. These technologies have been applied to studies of hypoxic brain injury, 22q11.2 deletion syndrome, Trisomy 21 (Down Syndrome), Trisomy 18, narcolepsy, Alzheimer's and Parkinson's Disease.
