  • Titilola Falasinnu

    Titilola Falasinnu

    Assistant Professor of Medicine (Immunology and Rheumatology) and, by courtesy, of Anesthesiology, Perioperative and Pain Medicine (Adult Pain)

    BioI am primarily a lupus researcher and identify as a pain scientist and methodologist in this field. Systemic lupus erythematosus (SLE) disproportionately affects women and racial minorities and is the fifth most common cause of death among 15- to 24-year-old Black and Hispanic women in the U.S., highlighting its significant public health impact. More than half of patients with SLE experience chronic pain, often secondary to SLE itself or overlapping conditions (e.g., migraines, low back pain, fibromyalgia), contributing significantly to disability and impaired quality of life. Chronic pain is not merely a symptom but a disease in its own right—one that deserves the same rigorous study and clinical attention as comorbidities like kidney disease and cardiovascular disease in rheumatology. The enormous global burden of chronic pain underscores the urgent need for a clear, standardized definition of pain as a disease, particularly in autoimmune rheumatic diseases where pain can arise from inflammatory, nociplastic, and biopsychosocial mechanisms. Without recognizing pain as a distinct disease entity, its mechanisms remain poorly understood, and effective treatment strategies remain underdeveloped.

    I am a co-Principal Investigator of the Pain Intelligence Lab, where our mission is to advance the study of pain as a disease in rheumatology through two primary objectives. First, we develop and validate computational methods that enable clinicians and researchers to leverage electronic health records, administrative claims, and disease registries to study chronic pain as a distinct disease entity in rheumatology. By applying machine learning, natural language processing, and real-world data analysis, we seek to enhance pain phenotyping, classify distinct pain subtypes, and develop predictive models for treatment response. Second, we use a biopsychosocial framework to examine the predictive power of biomarkers and psychosocial measures in rheumatologic pain. By integrating biological, psychological, and social determinants of pain, we aim to conduct rigorous, patient-oriented research that translates targeted assessments into mechanistically informed, personalized treatment approaches for optimized clinical care. Ultimately, my long term career goal is to bridge the gap between research and clinical practice, ensuring that pain management in autoimmune rheumatic diseases is precise, equitable, and optimized for improved patient outcomes.

    Professor of Medicine (Immunology and Rheumatology), Emeritus

    Current Research and Scholarly InterestsMy lab of molecular and cellular immunology is interested in research in the general field of T cell activation and autoimmunity. We have identified and characterized a gene (GRAIL) that seems to control regulatory T cell (Treg) responsiveness by inhibiting the Treg IL-2 receptor desensitization. We have characterized a gene (Deaf1) that plays a major role in peripheral tolerance in T1D. Using PBC gene expression, we have provisionally identified a signature of risk and progression in T1D.

  • Tobias Lanz

    Tobias Lanz

    Assistant Professor of Medicine (Immunology and Rheumatology)

    BioTobias Lanz, MD is an Assistant Professor at the Institute for Immunity, Transplantation, and Infection and the Division of Immunology and Rheumatology at Stanford. His research focuses on B cell biology in neuroimmunological diseases and rheumatic diseases with neurological manifestations. He uses high-throughput screening technologies, and methods from structural and cell biology to identify new autoantigens and to understand how certain self-reactive B cells escape tolerance mechanisms. He is particularly interested in molecular mechanisms that explain the association between Epstein Barr Virus (EBV) and autoimmunity.
    Tobias went to medical school at the Eberhard Karls University in Tübingen, Germany and at the University College of London. He wrote his MD thesis at Dr. Michael Platten's laboratory at the Hertie Institute for Clinical Brain Research in Tübingen, Germany before joining Dr. Lawrence Steinman’s neuroimmunological laboratory at Stanford as a research scholar. After medical school he pursued his scientific and clinical training at the German Cancer Research Center (DKFZ) and the Department of Neurology at the University Hospital in Heidelberg, Germany. In 2015 he joined Dr. William Robinson’s lab at Stanford, where he investigated environmental triggers of autoimmunity, including viruses and milk consumption. In his most recent work, he characterized the B cell repertoire in the spinal fluid of patients with multiple sclerosis (MS) and identified molecular mimicry between EBV EBNA1 and the glial cellular adhesion molecule GlialCAM as a driver of neuroinflammation (Lanz et al., Nature, 2022). His long term objective is to leverage these newly discovered mechanistic insights to develop next-generation biomarkers and therapeutics for autoimmune diseases.
