Dr. Dashti's research encompasses three themes: (1) performance-based evaluation and mitigation of liquefaction hazard; (2) seismic performance of shallow underground structures; and (3) response and interdependencies among infrastructure systems during disasters. Each theme requires the development of state-of-the-art experimental and simulation models and probabilistic assessment techniques to quantify the risk of damage and propose reliable remediation strategies. Dr. Dashti's team distinguishes itself by its emphasis on fundamental research that has important practical implications for practicing engineers globally. In her recent work and the interdisciplinary research theme (IRT) that she leads in the college of engineering (titled RISE), she also strives to combine the study of infrastructure resilience with sustainability and environmental justice considerations.
