Dr. Cardi has a background in experimental modal analysis, signal processing, machine design, and control systems design. At Exponent, Dr. Cardi has mainly supported efforts in GPR (Ground Penetrating Radar), a vehicle-mounted system to detect IEDs buried in the ground. He has worked on automated detection algorithms, basic circuit board design, and various mechanical hardware design aspects of the system.
For his Ph.D. research at Georgia Tech, Dr. Cardi developed analytical models that could be used to predict cutting forces in metal turning operations. One application of these models was to predict chatteran undesirable phenomenon whereby the workpiece vibrates violently with respect to the cutting tool in certain machining configurations. Prior to his graduate studies, Dr. Cardi performed research in load identification and structural health monitoring both as an undergraduate at Purdue University and as an intern at Los Alamos National Laboratory. Here he developed a novel algorithm for a portable system embedded in a soldier’s bulletproof armor vest to predict the location and magnitude of a ballistic impact using acceleration measurements.
