Professional Interests
Dr. Rizzo's academic and professional interests are in the fields
of nondestructive testing/evaluation, structural health monitoring,
signal processing and automatic pattern recognition for real-time
prognosis of structures, and implementation of embedded sensor network
for health monitoring of civil, mechanical and aerospace structures.
Past work included the development of a rail flaw detection system
based on non-contact hybrid laser/air-coupled ultrasonic sensors
to improve the reliability and the speed inspection of current systems,
and on the development of a structural health monitoring system
for steel and composite cables. Current interests and active projects
focus on 1) the development of a new paradigm for NDE/SHM based
on the propagation of highly nonlinear solitary waves, 2) the NDE/SHM
of sign supports, 3) sound source localization by unidirectional
microphones, 4) advanced algorithms for soil moisture characterization.
