Professional Summary

The focus of my research and teaching have been in the core area of Systems/Controls, with specialization in the development and application of practical, nondestructive evaluation techniques for damage identification, system identification and parameter estimation, condition assessment, health monitoring, remote monitoring/sensing, and associated information technologies. This includes the development of all necessary hardware, software, and algorithms for instrumentation, signal processing and data interpretation. I have worked on extensive application of these techniques in the areas of civil infrastructure systems, biomedicine, and aerospace.
