    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, by courtesy, of Medicine in Immunology and Rheumatology and Obstetrics and 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.

    Professor of Anesthesiology, Perioperative and Pain Medicine (Pediatric)

    Current Research and Scholarly InterestsI am a Professor in the Department of Anesthesiology, Perioperative, and Pain Medicine at Stanford University School of Medicine and a clinical psychologist who evaluates and treats youth presenting with chronic pain in the Pediatric Pain Management Clinic (PPMC) at Stanford Children’s Health. My program of research aims to utilize a pain neuroscience psychology approach to gain a mechanistic understanding of cognitive and affective processes in pediatric pain, perform rigorous patient-oriented research that translates targeted assessment into mechanistically informed treatment approaches for optimal clinical care and leverage the ubiquity of digital health to enhance patient access and reach. Central to these goals are projects targeting adolescence and youth adults with chronic pain that encompass defining brain signatures of threat interpretation, evaluating the efficacy of graded exposure (NCT03699007), deriving a biosignature of improvement vs. persistence of pain and disability (NCT04285112), and evaluating the impact of virtual reality on pain rehabilitation (NCT04636177). These studies along with additional work examining the journey of pain care for youth with pain and their parents form a comprehensive research portfolio in the realm of understanding and treating chronic pain in young people. My long-term career goal is to lead a robust research program focusing on alleviating the suffering of youth and emerging adults with chronic pain.

  • Sidhartha Sinha

    Sidhartha Sinha

    Assistant Professor of Medicine (Gastroenterology and Hepatology)

    Current Research and Scholarly InterestsThere are two primary and overlapping emphases of my research, both of which are driven and united by needs-based innovation and translational potential:

    (1) Understanding the microenvironment of the inflamed versus normal gut in order to identify better therapeutic targets for people with immune-¬mediated GI disorders. Here, our investigations include understanding the influence and interactions of pharmacologic and dietary interventions on gut microbiome/metabolomic changes and the host immune response. In the context of providing patients with new understanding and solutions for their disease, I have led and advised on the design of both pilot and large clinical trials (including new FDA approved therapies) for anti-inflammatory therapies;

    (2) Applying novel approaches and technologies (including natural language processing, computer vision, and reinforcement learning) to identify and address unmet clinical needs. In this area we have ongoing and published efforts in my lab to validate and develop solutions to pressing clinical needs. We have developed/led new drug delivery technologies with a multidisciplinary team that have shown strong potential in ongoing human IBD clinical trials. My lab has utilized both supervised and unsupervised approaches to analyze social media discourse and unstructured data sets for identifying patient needs that are rarely addressed in clinical settings. We have gained insights into patient perceptions around preventative health interventions, such as health screening and diet, including the dearth of evidence-based dietary recommendations to treat IBD (despite strong patient desire for solutions in this domain).

  • Jan Skotheim

    Jan Skotheim

    Professor of Biology and, by courtesy, of Chemical and Systems Biology

    Current Research and Scholarly InterestsMy overarching goal is to understand how cell growth triggers cell division. Linking growth to division is important because it allows cells to maintain specific size range to best perform their physiological functions. For example, red blood cells must be small enough to flow through small capillaries, whereas macrophages must be large enough to engulf pathogens. In addition to being important for normal cell and tissue physiology, the link between growth and division is misregulated in cancer.
