The structural design decisions that we make for buildings and bridges subjected to extreme forces (such as earthquakes, fires, hurricanes) greatly affect how many deaths, how much damage, and how long a recovery time a community will have following an extreme event. One of my research areas examines multi-hazard resilience for structures in various contexts. In this section, research topics are listed in reverse chronological order (from the time that the research started). Our research began at the element level (e.g. columns and connections), broadened to the system level (entire buildings), and has recently progressed to the community level (examining the effect of buildings on the community in an extreme event).
