My activities over the years have included research on earthquake response of structures, the economic losses associated with the performance of water and transportation systems following earthquakes, and earthquake-induced fire losses. I have conducted research on the synthesis of structural systems in architecture, and a series of studies on the structural behavior of masonry in geometric structures such as historic vaults, arches, and domes. More recently I have studied the behavior of tensegrity structures, including their highly nonlinear response and vibration performance. In the field of robotics I directed research on path planning, geometric reasoning, force-cognitive excavation, tools to find energy-optimal manipulator paths, control of manipulators with flexible links, and dynamically stable (balancing) robots. I also directed work that used spatial grammars in processing spatial constraints in robot task planning applied to coal mining, and rule-based programming applied in simulation and planning for robotized building construction. Most recently I have been working on devices for civil infrastructure sensing, including MEMS ultrasonic phased arrays, MEMS transducers for acoustic emission testing, piezoelectric devices for power scavenging, wireless Lamb wave transducers in bridge girder geometries, and an IC microsensor to measure chloride concentration.
