Shigemoto Lab

Research

Our lab studies how individuals and communities recover and grow after adversity, such as disasters, trauma, and public health crises. Across our projects, we use longitudinal, multilevel, and structural equation modeling.


How people grow after adversity

We study how people adapt and grow after trauma and adversity. Our work focuses on personal growth initiative, rumination, and coping, and how these relate to posttraumatic growth over time. Some of our studies follow people day by day using daily diary methods.

Who has resources, and who loses them

After a disaster or crisis, people lose resources such as housing, income, and social support. We study who is more likely to lose these resources and how unequal access to resources affects recovery.

How communities recover and grow together

We study how communities shape recovery after hurricanes and public health crises. Our work looks at community resilience, social cohesion, and where people live. We are especially interested in how communities recover and grow together after disasters.
