His main research interests are in the development and application of probabilistic concepts and methods to civil and marine engineering, including:
structural reliability; life - cycle
cost analysis; probability - based assessment, design, and multi-criteria life - cycle optimization of structures and infrastructure systems;
structural health monitoring; life - cycle performance maintenance and management of structures and distributed infrastructure under extreme events (earthquakes, tsunamis, hurricanes, and floods); risk - based assessment and decision making; multi-hazard risk mitigation; infrastructure sustainability and resilience to disasters; climate change
adaptation; and probabilistic mechanics.
