Implementation Science & Health Systems

Implementation Science & Health Systems

The design, adaptation, and rigorous evaluation of digital, scalable, and community-based interventions to reduce the population burden of non-communicable diseases, mental health, and infectious disease, and their comorbidities, among the general population, and among those most disadvantaged and marginalized in China and the region. Implementation science approaches will be employed to ensure maintenance and long-term impact of intervention programs.


The World Health Organization developed Step-by-step, the first digital mental health intervention designed to address depression in diverse populations globally. Our research team is the first in Asia to engage in the cultural adaptation and evaluation of this program; we culturally adapted Step-by-Step for Chinese young adults, and for Overseas Filipino Workers.

Our clinical trials of Step-by-Step are ongoing.
