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 also leads iMPaCT-STEM, an effort that develops programming activities integrated within mathematics and physics courses. iMPaCT-STEM activities are intended to both introduce students to programming and to strengthen students' conceptual understandings of these courses' primary learning outcomes.
