    Collapse Overview
    I am a Faculty Fellow in Infectious Diseases (Research) in the Division of HIV, Infectious Diseases, and Global Medicine at the University of California San Francisco (UCSF). My research group (http://lolab.ucsf.edu/) studies the transmission of infectious diseases with an ultimate goal of informing public health policy. My research blends diverse computational methodologies, including tools of simulation modeling, decision analysis, machine learning, and microbial genomics. My interest spans across multiple infectious diseases including neglected tropical diseases, vaccine-preventable infections, and COVID-19. My research group is affiliated with the Experimental and Population-based Pathogen Investigation center (EPPIcenter).

    A large emphasis of my work is translating scientific evidence into public health policy. Our track record includes multiple studies that have changed policy in the fields of tropical diseases, HIV, and COVID-19. I work closely with policy organizations like the World Health Organization and the California Department of Public Health. From 2018-2021, I served as the lead writer and editor for the WHO guidelines on public health control and elimination of schistosomiasis. My work has been supported by grants from the Bill and Melinda Gates Foundation, California Department of Public Health, and World Health Organization. I received a BS in Bioengineering from Rice University and MD/PhD (Epidemiology) from Stanford University. I completed my clinical residency in internal medicine at UCSF, and am a clinical fellow in infectious diseases.

    My current research focuses on the following areas:
    (1) Public health strategies to control the COVID-19 pandemic
    (2) Public health strategies for tropical infections, such as helminths infections and typhoid fever
    (3) Vaccine-preventable infectious diseases in the United States
