Eva Silverstein
Professor of Physics
BioProfessor Silverstein conducts research in theoretical physics -- particularly gravitation and cosmology, as well as recently developing new methods and applications for machine learning.
What are the basic degrees of freedom and interactions underlying gravitational and particle physics? What is the mechanism behind the initial seeds of structure in the universe, and how can we test it using cosmological observations? Is there a holographic framework for cosmology that applies throughout the history of the universe, accounting for the emergent effects of horizons and singularities? What new phenomena arise in quantum field theory in generic conditions such as finite density, temperature, or in time dependent backgrounds?
Professor Silverstein attacks basic problems in several areas of theoretical physics. She develops concrete and testable mechanisms for cosmic inflation, accounting for its sensitivity to very high energy physics. This has led to a fruitful interface with cosmic microwave background research, contributing to a more systematic analysis of its observable phenomenology.
Professor Silverstein also develops mechanisms for stabilizing the extra dimensions of string theory to model the accelerated expansion of the universe. In addition, Professor Silverstein develops methods to address questions of quantum gravity, such as singularity resolution and the physics of black hole and cosmological horizons.
Areas of focus:
- optimization algorithms derived from physical dynamics, analyzing its behavior and advantages theoretically and in numerical experiments
- UV complete mechanisms and systematics of cosmic inflation, including string-theoretic versions of large-field inflation (with gravity wave CMB signatures) and novel mechanisms involving inflaton interactions (with non-Gaussian signatures in the CMB)
-Systematic theory and analysis of primordial Non-Gaussianity, taking into account strongly non-linear effects in quantum field theory encoded in multi-point correlation functions
-Long-range interactions in string theory and implications for black hole physics
- Concrete holographic models of de Sitter expansion in string theory, aimed at upgrading the AdS/CFT correspondence to cosmology
- Mechanisms for non-Fermi liquid transport and $2k_F$ singularities from strongly coupled finite density quantum field theory
- Mechanisms by which the extra degrees of freedom in string theory induce transitions and duality symmetries between spaces of different topology and dimensionality -
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 errors in clinical decision making for female-predominant diseases including lupus and multiple sclerosis. This work evaluates this bias in multiple clinical specialties, including rheumatology, neurology, and primary care, and uses mixed methods. -
Lauren Simitz
Ph.D. Student in Aeronautics and Astronautics, admitted Autumn 2021
BioHi there! I'm an aerospace engineer, chemist, and geoscientist striving to both protect our world and advance technologies to explore new ones. Sustainability, teaching, and DEI are just as strong of passions, in and outside of the aerospace sector.
My work in industry (Chevron, SpaceX, Benchmark, Boeing) and academia catalyzed my interest in advancing sustainable, safe propulsion and energy systems. As a Stanford PhD candidate in the Hypersonics, Propulsion, and Energy Laboratory (HyPEL) working under Professor Ronald Hanson, I employ fluid mechanics, heat transfer, and chemical kinetics to experimentally probe combustion behavior. -
