Nirao Shah
Professor of Psychiatry and Behavioral Sciences (Major Laboratories and Clinical Translational Neurosciences Incubator), of Neurobiology and, by courtesy, of Obstetrics and Gynecology
On Leave from 09/23/2024 To 12/13/2024Current Research and Scholarly InterestsWe study how our brains generate social interactions that differ between the sexes. Such gender differences in behavior are regulated by sex hormones, experience, and social cues. Accordingly, we are characterizing how these internal and external factors control gene expression and neuronal physiology in the two sexes to generate behavior. We are also interested in understanding how such sex differences in the healthy brain translate to sex differences in many neuro-psychiatric illnesses.

Julia Fridman Simard
Associate Professor of Epidemiology and Population Health, of Medicine (Immunology & Rheumatology) and, by courtesy, of Obstetrics and Gynecology (Maternal Fetal Medicine)
BioJulia Fridman Simard, ScD, is an Associate Professor of Epidemiology & Population Health, and of Medicine in Immunology and Rheumatology and Obstetrics and, by courtesy, Gynecology in Maternal Fetal Medicine at Stanford University School of Medicine.
Dr. Simard earned her Masters and Doctorate of Science in Epidemiology degrees at the Harvard School of Public Health. During that time she trained with investigators at the Section of Clinical Sciences, Division of Rheumatology, Immunology, and Allergy at Brigham and Women’s Hospital and the Cardiovascular Epidemiology Research Unit at Beth Israel Deaconess Medical Center. In 2008, Dr. Simard relocated to Sweden to begin a Postdoctoral Fellowship in Clinical Epidemiology at the Karolinska Institutet in Stockholm. She became an Assistant Professor in their Clinical Epidemiology Unit in 2011, and was later honored with a Karolinska Institutet Teaching Award. Leveraging the population-based registers of Sweden, Dr. Simard initiated a national register linkage study to examine the utility of registers in Systemic Lupus Erythematosus (SLE) research and develop an extensive data repository for future epidemiologic investigations.
While maintaining a close collaboration with the Karolinska Institutet, she joined Stanford’s Epidemiology faculty in 2013. Dr. Simard studies outcomes such as malignancy, stroke, infection, and mortality, in patients with systemic autoimmune rheumatic diseases with a focus on systemic lupus erythematosus. Recently her primary research focus has shifted to the intersection between reproductive epidemiology and rheumatic disease fueled by a K01 career development award from the NIH (NIAMS) to study maternal and fetal outcomes in systemic lupus pregnancy. This led to collaborations with colleagues at Stanford, throughout the US, and abroad, and a series of projects focused on the diagnosis of preeclampsia and associated risks in pregnant women with systemic lupus. Dr. Simard was awarded a Peter Joseph Pappas Research Grant from the Preeclampsia Foundation for her lab's work examining preeclampsia risk in high-risk populations, and a McCormick Faculty Award from Stanford Medicine to take important steps towards disentangling preeclampsia from lupus nephritis. Dr. Simard is leading an international study of hydroxychloroquine in lupus pregnancy leveraging mixed methods in partnership with qualitative researchers, patients, clinicians, and epidemiologists in Sweden, Canada, and in the United States.
In addition to these issues of misclassification in reproductive rheumatology questions, Dr. Simard's lab is also interested in how misclassification, missed opportunities, and misdiagnosis contribute to disparities in complex conditions such as systemic lupus. In addition to methodologic issues around misclassification and bias and the largely clinical epidemiology focus of her work, Dr. Simard's work examines social determinants of health and health disparities. Dr. Simard was recently awarded an R01 from NIH (NIAID) to study the role of cognitive and unconscious bias in clinical decision making for female-predominant diseases including lupus. -

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. -

Virginia D. Winn, MD, PhD
Professor of Obstetrics and Gynecology (Reproductive, Perinatal & Stem Cell Biology Research)
Current Research and Scholarly InterestsThe Winn Laboratory seeks to understand the unique biological mechanisms of human placentation. While the placenta itself is one of the key characteristics for defining mammals, the human placenta is different from most available animal models: it is one of the most invasive placentas, and results in the formation of an organ comprised of cells from both the fetus and the mother. In addition to this fascinating chimerism, fetal cells are deeply involved in the remodeling of the maternal vasculature in order to redirect large volumes of maternal blood to the placenta to support the developing fetus. As such, the investigation of this human organ covers a large array of biological processes, and deals not only with understanding its endocrine function, but the physiologic process of immune tolerance, vascular remodeling, and cellular invasion.
