    Rebecca M. Gardner

    Ph.D. Student in Epidemiology and Clinical Research, admitted Autumn 2022

    BioMy research interests are in maternal nutrition and well-being, with a current focus on hyperemesis gravidarum (HG)—severe nausea and vomiting during pregnancy that often causes significant maternal undernutrition and poor antepartum and postpartum mental health, and is the leading cause of hospitalization in early pregnancy. I study HG from several angles: the environmental exposures that may exacerbate it, including ambient air pollution and wildfire smoke, and whether these contribute to HG-related hospitalization; and its downstream consequences for both mothers and children, including hypertensive disorders of pregnancy such as preeclampsia, preterm birth, and neurodevelopmental conditions in childhood such as autism. More broadly, I am interested in hypertensive disorders of pregnancy, preterm birth, and gestational diabetes, and their subsequent effects on offspring. Methodologically, I am drawn to applying causal inference methods traditionally used in economics to questions in public health.


    Before starting a PhD, I was a biostatistician in the Quantitative Sciences Unit at Stanford for four years where I co-authored over thirty publications, collaborating with clinicians on various domains including developmental behavioral pediatrics, reproductive endocrinology & infertility, oncology, and clinical trials. I completed my MS in Statistics at Brigham Young University in 2016, where I collaborated with cardiologists to develop a new approach to diagnose rheumatic heart disease in pediatric patients in Samoa for my Master's thesis.

  • Nicole Gladish

    Nicole Gladish

    Research Fellow, Epidemiology and Population Health

    BioDr. Nicole Gladish is a Research Fellow in the Department of Epidemiology and Population Health at Stanford University. Her work integrates genetic, epigenetic, and population-level data to understand how biological and environmental factors interact to shape health disparities and influence trajectories of healthy aging. In addition to exploring molecular mechanisms, she conducts applied research on health policy interventions developing and refining tools like deprivation indices to inform equitable decision-making at the systems level.

    Dr. Gladish earned her Ph.D. in Medical Genetics from the University of British Columbia (UBC), where her thesis focused on how early-life adversity, such as low socioeconomic status and abuse, affects DNA methylation patterns. This work aimed to elucidate the biological mechanisms that predispose individuals to chronic diseases such as cardiovascular disease, diabetes, and cancer.

    At Stanford, she continues to investigate the interplay between social determinants and biological risk, with a growing emphasis on translational research. Her development of improved social deprivation indices supports more accurate identification of disadvantaged communities, informing public health funding, service allocation, and structural interventions across the U.S.

    Dr. Gladish's work bridges molecular epidemiology and public policy, aiming to ensure that scientific insights translate into measurable improvements in population health.

    Postdoctoral Scholar, Epidemiology

    BioChris Heitzig is a New Map of Life Postdoctoral Fellow in the Department of Epidemiology and Population Health. An economist by training, his research develops models to examine healthy aging across the life course, with a particular emphasis on identifying causal pathways and key points of policy intervention to improve well-being in later life. A central focus of his work is the socioeconomic impact of undiagnosed metabolic disorders—how these conditions manifest, the costs of leaving them untreated, and the potential for interventions to improve detection and outcomes. His research combines insights from economics and public health with machine learning methods for causal inference.

    Before joining Stanford, Chris served in research roles at the Brookings Institution and the World Bank. At Brookings, he managed a $1.5 million research grant investigating how technological change is reshaping employment in Africa. At the World Bank, he designed randomized controlled trials to measure the causal effects of health and employment programs and served in an operational role as the day-to-day lead for a $20 million job transition program. Chris holds a PhD in Economics from the Institute of Development Studies, an MPhil in Economics from the University of Oxford, and a BA in Economics from Saint John’s University.
