Research Interests

My research focuses on: 1) exploring the individual and community drivers of vulnerability to acute and chronic natural hazards; and 2) understanding how communities and individuals perceive and develop adaptation strategies in response to these hazards.  I am particularly interested in how natural hazard mitigation decision-making at the institutional level can create adaptation measures that lead to uneven response and recovery.  As a social scientist, I use mixed-methods approaches (e.g. qualitative, quantitative, and GIS) and work to deeply engage a wide variety community members and stakeholders to co-produce feasible adaptation strategies.   My current work analyzes equitable distribution of adaptation measures for chronic (e.g. erosion, flooding) and acute (e.g. earthquake/tsunami) hazards in Oregon’s coastal regions; the relationship between social vulnerability and water pipe damage and repair after the Tubbs (Santa Rosa, CA) and Camp Fires (Paradise, CA); and co-producing adaptation strategies to manage stresses to the food-energy-water nexus in the Umatilla Basin (OR).
