  • James Spudich

    James Spudich

    Douglass M. and Nola Leishman Professor of Cardiovascular Disease, Emeritus

    Current Research and Scholarly InterestsThe general research interest of this laboratory is the molecular basis of cell motility, with a current emphasis on power output by the human heart. We have three specific research interests, the molecular basis of energy transduction that leads to ATP-driven myosin movement on actin, the biochemical basis of the regulation of actin and myosin interaction and their assembly states, and the roles these proteins play in vivo, in cell movement, changes in cell shape and muscle contraction.

  • Gayathri Srinivasan OD, MS

    Gayathri Srinivasan OD, MS

    Clinical Associate Professor, Ophthalmology

    BioDr. Srinivasan is a Clinical Associate Professor in the Department of Ophthalmology at Stanford University. Her clinical focus is in the management of concussion-related vision disorders. Dr. Srinivasan's research interests are amblyopia, strabismus, and concussion-related vision disorders. She serves as an investigator for ongoing clinical studies in the Vision Development and Oculomotor lab headed by Dr. Tawna Roberts.

  • Randall Stafford

    Randall Stafford

    Professor of Medicine (Stanford Center for Research in Disease Prevention)

    Current Research and Scholarly InterestsAs Director of the SPRC Program on Prevention Outcomes and Practices, my work focuses on cardiovascular disease treatment and prevention, the adoption of new technology and practices, and patterns of physician practice, particularly medication prescribing. Specific interests include measuring and improving the quality of outpatient care, disparities in health care by race, gender, age and socioeconomic status, and interventions to improve prevention outcomes.

  • Marcia L. Stefanick, Ph.D.

    Marcia L. Stefanick, Ph.D.

    Professor (Research) of Medicine (Stanford Prevention Research Center), of Obstetrics and Gynecology and, by courtesy, of Epidemiology and Population Health

    Current Research and Scholarly InterestsMarcia L. Stefanick, Ph.D is a Professor of Medicine Professor of Obstetrics and Gynecology, and by courtesy, Professor of Epidemiology and Population Health at Stanford University School of Medicine. Dr. Stefanick’s research focuses on chronic disease prevention (particularly, heart disease, breast cancer, osteoporosis, and dementia) in both women and men. She is currently the Principal Investigator the Women’s Health Initiative (WHI) Extension Study, having been the PI of the Stanford Clinical Center of the landmark WHI Clinical Trials and Observational Study since 1994 and Chair of the WHI Steering and Executive Committees from 1998-2011, as well as PI of the WHI Strong and Healthy (WHISH) Trial which is testing the hypothesis that a DHHS-based physical activity intervention, being delivered to a multi-ethnic cohort of about 24,000 WHI participants across the U.S., aged 68-99 when the trial started in 2015, will reduce major cardiovascular events over 8 years, compared to an equal number of “usual activity” controls. Dr. Stefanick is also PI of the Osteoporotic Study of Men (MrOS) which is continuing to conduct clinical assessments of bone and body composition in survivors of an original cohort of nearly 6000 men aged 65 and over in 2001. As founding Director of the Stanford Women’s Health and Sex Differences in Medicine (WHSDM, “wisdom”) Center, she plays a major role in promoting research and teaching on Sex and Gender in Human Physiology and Disease, Women’s Health and Queer Health and Medicine. Dr. Stefanick also plays major leadership roles at the Stanford School of Medicine, including as co-leader of the Population Sciences Program of the Stanford Cancer Institute, Stanford’s NCI-funded comprehensive cancer center.

    Dr. Stefanick obtained her B.A. in biology from the University of Pennsylvania, Philadelphia, PA (1974), then pursued her interest in hormone and sex difference research at the Oregon Regional Primate Research Center, after which she obtained her PhD in Physiology at Stanford University, focusing on reproductive physiology and neuroendocrinology, with exercise physiology as a secondary focus. Her commitment to human research led to a post-doctoral fellowship in Cardiovascular Disease Prevention at the Stanford Prevention Research Center, which has been her academic home for nearly 40 years.

  • Katherine Steffen

    Katherine Steffen

    Clinical Associate Professor, Pediatrics - Critical Care

    Current Research and Scholarly InterestsMy research interests focus on using dissemination and implementation science tools to study and enhance care provided to patients in the pediatric ICU. I have a background in human factors research and in implementation science and am also interested in clinical effectiveness and outcomes in the PICU.

  • Lea Steffes

    Lea Steffes

    Instructor, Pediatrics - Pulmonary Medicine

    BioDr. Steffes, a Wisconsin native, completed medical school and pediatric residency at the Medical College of Wisconsin. She then moved to the Bay Area and completed her clinical fellowship in pediatric pulmonary medicine at Stanford University in 2020. Additionally, Dr. Steffes received further post-doctoral training in the laboratories of Dr. Maya Kumar and Dr. David Cornfield, studying the cellular and molecular mechanism driving pulmonary vascular disease. In addition to her role as an Instructor in Pediatrics in the division of Pulmonary Medicine, Dr. Steffes is also completing an advanced clinical fellowship in Pulmonary Hypertension at Lucile Packard Children’s Hospital Stanford. Her clinical work consists of caring for patients with pediatric pulmonary and pulmonary vascular diseases such as pulmonary hypertension, bronchopulmonary dysplasia, interstitial lung disease, respiratory failure, chronic cough and asthma. Her research is focused on the vascular changes seen in pulmonary hypertension, more specifically understanding the cellular characteristics of occlusive neointimal lesions, the abnormal cells that block pulmonary blood flow in pulmonary hypertension. In her most recent work, Dr. Steffes identified a subset of healthy vascular smooth muscle cells that are the cell of origin for the pathologic neointimal cells and a specific signaling pathway, that when blocked, inhibits the formation of neointimal lesions.

    Dr. Steffes is currently employing advanced single cell sequencing technologies to further understand neointimal cells with the ultimate goal identifying new therapies for pulmonary hypertension, a fatal disease with no known cure.

  • Lawrence Steinman, MD

    Lawrence Steinman, MD

    George A. Zimmermann Professor and Professor of Pediatrics

    Current Research and Scholarly InterestsOur laboratory is dedicated to understanding the pathogenesis of autoimmune diseases, particularly multiple sclerosis. We have developed several new therapies for autoimmunity, including some in Phase 2 clinical trials, as well as one approved drug, natalizumab. We have developed microarray technology for detecting autoantibodies to myelin proteins and lipids. We employ a diverse range of molecular and celluar approaches to trying to understand multiple sclerosis.
