    Collapse overview
    Dr. Nguyen is a substance use researcher whose research program focuses on reducing the co-use of tobacco and cannabis. She has employed a variety of research methods (e.g., human-centered design, ecological momentary assessment, and mixed methods) to address important issues in tobacco and cannabis use and co-use. Her current projects are applying mobile health technology, AI/machine learning, and implementation science to develop smartphone interventions targeting vaping cessation and co-use of tobacco and cannabis among young people.

    Dr. Nguyen founded the HEARTY lab (https://heartylab.ucsf.edu). Her lab's mission is to provide actionable insights and novel solutions to reduce substance use and promote public well-being.
