    Nathan Lo

    Assistant Professor of Medicine (Infectious Diseases) and, by courtesy, of Epidemiology and Population Health

    Current Research and Scholarly InterestsOur research group is interested in studying the transmission of infectious diseases and impact of public health interventions with an ultimate goal of informing public health policy. We study a diverse set of pathogens, both domestically and internationally, including vaccine-preventable infections (including COVID-19) and neglected parasitic diseases (such as schistosomiasis). Our group applies diverse computational methodologies, including tools from fields of epidemiology, mathematical and statistical modeling, simulation, and policy analysis.

    A large emphasis of our work is translating scientific evidence into public health policy. Our track record includes multiple studies that have changed policy in the fields of neglected parasitic diseases and COVID-19. We work closely with policy organizations like the World Health Organization and the California Department of Public Health. Nathan was the lead writer of the World Health Organization guidelines on schistosomiasis (2022) and strongyloidiasis (2024).

    Our current research focuses on the following areas:
    (1) Vaccine-preventable infectious diseases (including COVID-19) in the United States, with a focus on studying vaccines and transmission dynamics
    (2) Public health strategies for control and elimination of globally important neglected infectious diseases, such as helminths infections (schistosomiasis, strongyloidiasis) and typhoid fever

    Our currently funded NIH projects include:
    (1) Real-time predictive modeling for public health departments to control infectious diseases (DP2 AI170485)
    (2) Precision mapping of Schistosoma mansoni risk for targeted public health control and elimination (R01 AI179771)

    Hiring
    We are seeking to fill multiple research positions at all levels. Candidates interested in working on computational public health research related to infectious diseases with a strong quantitative background are highly encouraged to apply.

  • Kyle Loh

    Kyle Loh

    Assistant Professor of Developmental Biology (Stem Cell)

    BioHow the richly varied cell-types in the human body arise from one embryonic cell is a biological marvel and mystery. We have mapped how human embryonic stem cells develop into over twenty different human cell-types. This roadmap allowed us to generate enriched populations of human liver, bone, heart and blood vessel cells in a Petri dish from embryonic stem cells. Each of these human cells could regenerate their cognate tissue upon injection into respective mouse models, with relevance to regenerative medicine. In addition to developmental and stem cell biology, we have an emerging interest in exploring deadly biosafety level 4 viruses together with our collaborators.

    Kyle attended the County College of Morris and Rutgers, and received his Ph.D. from Stanford (working with Irving Weissman), with fellowships from the Hertz Foundation, National Science Foundation and Davidson Institute for Talent Development. He then continued as a Siebel Investigator, and later, as an Assistant Professor and The Anthony DiGenova Endowed Faculty Scholar at Stanford, where he is jointly appointed in the Department of Developmental Biology and Institute for Stem Cell Biology & Regenerative Medicine. Kyle is a Packard Fellow, Pew Scholar, Human Frontier Science Program Young Investigator and Baxter Foundation Faculty Scholar, and his research has been recognized by the NIH Director's Early Independence Award, Forbes 30 Under 30, Harold Weintraub Graduate Award, Hertz Foundation Thesis Prize and A*STAR Investigatorship.

    Assistant Professor of Cardiothoracic Surgery (Pediatric Cardiac Surgery)

    Current Research and Scholarly InterestsOur lab aims to understand the biomechanics that govern a wide spectrum of congenital heart defects, and how those biomechanics change with contemporary operative repair strategies. We simulate operations virtually via CFD, and in ex vivo and in vivo animal models, and analyze how the changes we make alter fluid flow, pressure, and stresses throughout the system. We hope that these experiments can impact and optimize existing techniques that translate quickly to the operating room.
