  • Jane Parnes

    Jane Parnes

    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

    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.

  • 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.

  • Michele Lanpher Patel

    Michele Lanpher Patel

    Instructor, Medicine - Stanford Prevention Research Center

    BioMichele L. Patel, PhD is an Instructor in the Stanford Prevention Research Center at the Stanford University School of Medicine. Trained as a clinical health psychologist, Dr. Patel conducts research to optimize scalable digital health interventions for adults with obesity. She leads clinical trials that test innovative strategies to address the critical challenge of suboptimal engagement in digital interventions.

    Dr. Patel's research is supported by an NIH career development award (K23; 2022-2027). Her recent Spark trial investigated the most potent combination of self-monitoring strategies in a behavioral weight loss intervention among 176 adults with overweight or obesity. Results are expected to be published in 2026.

    She is also testing other strategies to promote engagement, weight loss, and health. This includes the impact of easier vs. harder goals, and the effect of high-frequency, low-friction behavioral strategies. Her work leverages the Multiphase Optimization Strategy (MOST) to systematically identify intervention strategies that maximize effectiveness while minimizing patient burden.

    Dr. Patel received her PhD in clinical psychology from Duke University. She completed her clinical internship at the VA Palo Alto with a specialization in behavioral medicine, followed by a postdoctoral fellowship (T32) at the Stanford Prevention Research Center. She currently serves as the Chair of the Optimization of Behavioral and Biobehavioral Interventions special interest group in the Society of Behavioral Medicine.

    Primary Research Interests:
    -- Optimizing digital interventions for obesity treatment and prevention
    -- Leveraging behavioral science to create lower-burden self-monitoring strategies to improve engagement and outcomes
    -- Identifying psychosocial factors (including health literacy and self-efficacy) that influence treatment success

    Methodological Expertise:
    -- Randomized clinical trials, including factorial designs and embedded trials
    -- Systematic reviews
    -- Signal detection analysis
