Dr. Dieckman has a background in acoustic modeling, signal processing, and machine learning with a degree concentration in Nondestructive Evaluation. He is the author or co-author on more than 30 conference presentations, reports, and patent applications, covering a wide range of topics. Results from his work have been presented across the United States and in Mexico, Canada, France, and Spain. Recent projects include development of an ultrasonic system to detect counterfeit microelectronic components, design of an acoustic method to benignly exclude pest birds from a geographic area, and numerical simulations of acoustic scattering.

As part of his dissertation research, Dr. Dieckman investigated a number of sensor modalities for mobile robotics applications, including passive thermal infrared, active near-infrared depth-mapping, a coffee-can radar, and echolocation using an acoustic parametric array. This work identified a new low-cost, long-range acoustic echolocation sensor which, coupled with advanced signal processing and machine learning algorithms, allows the automated detection and classification of oncoming vehicles at distances exceeding 50 m.

Dr. Dieckman is a co-founder of the Wavelet Signal Processing and Nondestructive Evaluation Systems Testing (WaSP-NEST) Lab at the Sonalysts Waterford campus, where he is directing the exploration of new methods of ultrasonic non-destructive evaluation of complex structures using advanced signal processing and machine learning approaches. Recent projects include guided wave ultrasonic inspection of thermal-spray coatings for ship structures, Pareto optimization of UUV operations, data mining of sonar operator performance metrics, and physical modeling of satellite motion for software training systems.
