Dr. Freudenthal has developed techniques for implementing secure and self-organizing systems, coordinating parallel and distributed computations, and recognizing objects in radar imagery. His current research examines robust and autonomic approaches for resource management in delay-intolerant devices such as smartphones, and the balancing of energy consumption with performance in high performance parallel systems.Dr. Freudenthal is the inventor of vocal Fundamental Frequency Accentuation (FFA) which appears to dramatically improve peoples' ability to modulate and observe others' modulation of voice pitch, cadence, and volume. Several utility patents have been filed. Research efforts are examining how FFA impacts predictive and receptive vocal communication abilities related to prosody commonly affected by Autistic Spectrum Disorder.Dr. Freudenthal is active in education research. In the past, he developed high school and college curricula related to programming, mathematics, and physics. He presently contributes to the design of curricula related to parallel and distributed computing.
