    Assistant Professor of Medicine (PCOR)

    BioDavid Chan, MD, PhD, is an Assistant Professor of Medicine at the Stanford School of Medicine, an investigator at the Department of Veterans Affairs, and a Faculty Research Fellow at the National Bureau of Economic Research. Drawing on labor and organizational economics, he is interested in studying how information is used in health care, how this affects productivity, and implications for design. He is the recipient of the 2014 NIH Director’s High-Risk, High-Reward Early Independence Award to study the optimal balance of information in health information technology for patient care.

    Dr. Chan received master’s degrees in policy and economics from the London School of Economics and Oxford University, where he studied as a Marshall scholar. He holds a medical degree from UCLA and a PhD in economics from MIT. He trained in internal medicine at Brigham and Women’s Hospital and was an instructor of medicine at Harvard Medical School, prior to coming to Palo Alto, where he currently is a hospitalist at the Department of Veterans Affairs, Palo Alto.

    Stanford Student Employee, Medicine - Med/PCOR

    BioI am a PhD candidate in the Department of Biomedical Data Science at Stanford University, advised by Euan Ashley and Trevor Hastie. My research focuses on promoting health equity by addressing disparities in chronic illness and mass incarceration. My work centers around integrating data from disparate sources using a variety of quantitative approaches such as machine learning, simulations, and inference.

    I am interested in occupational, socioeconomic, and racial inequities and their relation to public health. My most recent projects include:
    1. Projected geographic disparities in healthcare worker absenteeism from COVID-19 school closures
    2. Frequency of Routine Testing for Covid-19 in High-risk Healthcare Environments to Reduce Outbreaks
    3. Testing strategies for airline travel during the COVID-19 pandemic
    4. Studying decarceration, ongoing risks, and risk factors from Covid-19 in the California State Prison System
    5. Quantifying disparities in testing and vaccine acceptance in California prisons

    I am grateful for the support of the Stanford Graduate Fellowship and the National Science Foundation Graduate Fellowship. Before coming to Stanford, I obtained my Bachelor of Science in Applied Mathematics at the University of California Los Angeles, where I was fortunate to conduct computational genomics research under the advisement of Xinshu (Grace) Xiao. As an undergraduate, I was also honored to conduct research with Rachel Martin, Carter Butts, and Pardis Sabeti as part of NSF REU and Harvard Systems Biology Summer Research Programs. I have also worked on machine learning/data science teams at Adobe Systems and Quora.
