• A key challenge to reduce the burden of preventable disease for all is to understand the interplay between environment, biology, psychology, and people, surrounding key risk health behaviors. These factors operate across different scales and call for multimodal approaches.

• Digital data (e.g., from smartphones and wearables) and brain scanning (e.g., neuroimaging) can be combined to reveal individual and shared correlates of thoughts, feelings, influences, and behaviors in real-world settings; and to help develop more precise diagnostic tools and health interventions. My research takes on this interdisciplinary perspective to study the following questions:
  

What happens in human brain when undergoing psychological interventions,
and what mechanisms are associated with behavior change?

How do social interactions, and how we think about others,
relate to health-related social influence processes in daily life?

How to develop better diagnostic tools and digital interventions
to promote health and well-being?
